Sienna Miller

Sienna Miller is expecting her first child.

The actress, whose on-and-off relationship with Jude Law has made for some major tabloid fodder over the years, has reportedly been knocked up by Tom Sturridge, her boyfriend since early 2010.

Despite the news, a source tells Us Weekly the couple doesn't "have plans right away to marry, if at all."

The insider adds that Miller's "friends are really happy with her relationship with Tom" because he's "mature and he's a good guy," a not-so-veiled diss of Law, who famously cheated on Sienna in 2006 with his children's nanny.

Miller and Sturridge announced the pregnancy to family members and pals in London over the holidays and then took a vacation in Paris, this mole says, concluding simply: "They're really good together."

Jude Law and Sienna Miller have broken up, according to reports. Again. They couple had been together since 2009. They dated from 2004-2006 as well.

Fortunately, there was no intercourse with a nanny involved or anything like that.

"It is mutual, amicable and they are still friends," a friend of the two stars says.

According to the friend, the pair separated a couple of weeks ago. "It was entirely an end-of-the relationship decision," the source says. "It had run its course."

Adds a rep for the Repo Men star: "I can confirm that Jude Law and Sienna Miller are no longer in a relationship." No further details were provided.

The actors got engaged in Christmas 2004, only to part a few years later. Then they reunited in the fall of 2009 and had been dating ever since.

Don't worry, Halle Berry and Sienna Miller: you're in the news for non-love life related reasons today.

The actresses, whose romances are well-documented by the press (Berry is dating Olivier Martinez, for the record; while Miller has probably broken up and made up with Jude Law twice in the time it took you to read this), were spotted wearing the same Isabel Marant blouse at different public events over the last few weeks.

Berry covered it with a vest. Miller did not. Who wore it better? You decide!

Sienna Miller says she's not trying to win any popularity contests.

That is a good thing, as wrecking homes is not the place to start.

Still, you can't deny how good the G.I. Joe actress looks on film, or the new UK issue of GQ for that matter. Here's a gorgeous photo of the 27-year-old star ...

Like her or not, the girlfriend of Balthazar Getty continues to find a lot of work in successful movies, and is not likely to go away anytime soon.

Home-wrecker extraordinaire Sienna Miller looks like she is officially back in the arms of age-inappropriate, marriage-inapproriate, kids-inappropriate lover Balthazar Getty.

Balthazar, who was last seen kissing Sienna Miller nude while married to his wife and the mother of his four children, was thought to have split with the wrecker of homes.

But the sexy pair who we assumed to be former lovebirds were spotted on a break in the romantic Italian town of Positano, and kissed each other at a restaurant.

They joined a group of family and friends for a meal at a restaurant called Lo Scoglio. But Sienna mustn't have been satisfied by her menu choice, as soon enough, she was spotted trying to devour the former Brothers & Sisters star's ear.

Sienna was also said to have arrived with her mom Jo on Friday, which makes their reported split with Balthazar even more unlikely, if he’s now got her approval.

GETTY UP: Balt and Sienna are so hitting it.

This encounter comes just a few weeks after Sienna spoke about the break-up in Vogue magazine, telling the publication “[A friend] took me out to lunch - funnily enough to a restaurant called Balthazar, which I thought was hilarious."

"But she never commented on the irony of that - and she said, ‘You’ve been through hell, and you need to talk about it with someone,’” Miller added then.

Did the woman who wrecks homes like it's her job just pull one over on Vogue? And the rest of us? How much longer until she gets topless on the beach?

Sienna Miller has moved on from her fling with Brothers & Sisters star Balthazar Getty.

According to reports, the promiscuous actress has wasted little time in conquering her latest hook-up: mediocre actor Josh Hartnett.

Earlier this week, the duo was spotted at London's Shoreditch House.

“They definitely looked like a couple — and a good looking one at that," said a source. "At one point, they were holding hands across the table, but they quickly hid them underneath. They looked really cozy as they dined, gazing into each other’s eyes, smiling and laughing. They continued talking and drinking until very late into the evening — there was definitely a buzz in the air."

Josh Hartnett isn't married, nor does he have a nanny with which he can cheat on Sienna Miller. Looks like the actress has finally found her ideal mate!

Yes, Sienna Miller and Balthazar Getty have officially split. Call us crazy, but we sort of saw this one coming awhile back. Like the day they hooked up.

"I'm single at the moment, and I'm completely happy with that," the actress said Friday evening at the Hollywood Dominoes: VIP Launch in London.

"It's nice not to be in a relationship that the press constantly want to scrutinize and discuss," Miller added. "I'm cool with being on my own."

Miller and Getty's whirlwind romance first made headlines in July when Getty - who was married at the time - was photographed kissing Sienna Miller nude.

CALLING MARRIED GUYS: Sienna Miller is back on the prowl!

Sienna, 26, later sued two British newspapers and a celebrity photo agency for breach of privacy for publishing the steamy shots of her and Getty.

After the pics' release, the Brothers & Sisters actor, 33, announced that he and his wife Rosetta, with whom he has four children, were separated.

In August, Miller's home in London was vandalized with the word "slut." Not the most creative insult, but hard to argue with the graffiti artists' point.

Jo Miller, whose daughter Sienna has been involved in a number of high profile relationships, is asking celebrity gossip outlets for a ceasefire on their "feeding frenzy," referring to coverage of the actress' affair with married actor Balthazar Getty.

"You can't understand how a woman seeing a man who has been separated from his wife [Rosetta Getty] for months can cause such a scandal," Mrs. Miller told the U.K.'s Daily Express. "It's awful, I can't tell you. You wonder when it's all going to stop."

Then again, acquaintances of Rosetta Getty have said her and her husband were "in no way separated" when the Brothers & Sisters star began dating Miller. One friend said:

"Any implication otherwise is an absolute lie. Balthazar's affair has been utterly devastating to Rosetta and her family."

On July 21, Getty released a statement announcing he and Rosetta are separated.

"Yes, they're living separate lives at the moment – because of his shenanigans," said another friend. "It's disappointing that [Getty and Miller] are flaunting this so publicly. There are four children involved. Their oldest, Cassius, is mature enough to understand something's not right."

It's hard to find fault with that statement. After all, Mrs. Miller, it's our job to report on celebrity news - and when your daughter goes topless for all to see, laying a smooch on her new man, that's a newsworthy story.

Recent topless photos of Sienna Miller kissing Balthazar Getty have shoved this steamy affair into the spotlight.

The actress - best known for her flings, which include a roller-coaster relationship with Jude Law and one with Rhys Ifans that ended just weeks ago - has been quietly dating Getty for "at least two months," a source said to People Magazine.

Here's a shock: Sienna Miller is involved in a controversial relationship.

While the same source confirmed that Getty and wife Rosetta "have been living separate lives for a while," that doesn't mean the timing of the affair isn't hurtful.

Balthazar and his wife were married in May 2000 and had their fourth child together 10 months ago. It's enough to make Alex Rodriguez proud of the actor for such inappropriate behavior so soon after the birth of a baby.

"It's humiliating," a friend said about the Miller/Getty relationship. "Rosetta left the country to protect the kids, and he continues to see Sienna publicly."

It didn't take long for Sienna Miller to get past ex-boyfriend Rhys Ifans.

The promiscuous Brit was recently spotted laying a smooch on new boy toy, Balthazar Getty. And she wasn't wearing any clothing while doing it!
