Shockingly, Sienna Miller has wasted little time moving on from Rhys Ifans.

The British actress - who is busy filming G.I. Joe: Rise of Cobra - is reportedly getting cozy with Balthazar Getty. Yes, the same guy that’s still married and welcomed his fourth child into the world in October. Balthazar is an heir to the Getty Oil fortune.

Sienna Miller and Balthazar Getty are a rumored couple no one really cares about.

A source told Great Britain’s The News of the World that the couple is trying to keep their affair quiet:

“They daren’t go out together, so they spend most of their time inside. When they do leave, they go separately.”

Sorry, Sienna and Balthazar. You can’t get anything past us!

Things between Rhys Ifans and Sienna Miller are not GR8.

According to UK’s The Sun, this couple has broken up after Miller caught Ifans going through her text messages. That’s not a LOL situation at all.

OMG, readers. Sienna Miller won’t be making out with Rhys Ifans anymore.

The newspaper went on to say that Ifans was jealous of the relationship between Sienna and ex-boyfriend Matthew Rhys. Said a source:

“He has been giving her a hard time lately, questioning her commitment to him and the time she puts into the relationship. When they are together they get on so well. But she can’t cope with his jealousy.”

Now that Miller and Ifans are broken up - and a week after George Clooney kicked Sarah Larson to the curb - we turn our attention to Stephanie Pratt and Brett Novek.

Can this celebrity couple rekindle our belief in love?

You may question the sanity of Sienna Miller - in fact, you pretty much have to - but don’t you dare question her love for Rhys Ifans.

The British actress recently told her country’s Elle magazine that it takes very little for her to gush about her man:

“When his name is mentioned, it makes me smile like a fool because I instantly think of him and it makes me happy. He does just make me happy. I totally love Rhys.”

Sienna Miller and Rhys Ifans: In love, insane.

Sorry, Jude Law. But it appears as though Miller has finally moved on. We hope the various women you take home every night are keeping you comfort at least.

Miller, meanwhile, is next starring in a remake of the classic cartoon G.I. Joe. There’s no truth to the rumor that producers thought of renaming it G.I. Ho in her honor. Zing!

Look out world: Sienna Miller has babies on the brain!

During her roller-coaster romance with Jude Law, the actress says bearing children was never discussed. But it looks like motherhood may now be an option with boyfriend Rhys Ifans.

“I really want babies – I always have,” Miller told the June U.K. edition of InStyle magazine during a baby shower for her elder sister Savannah.

“I mean, I’m nearly 27 and you have to think about these things, don’t you?” said Miller. “And Sav proves you can work and be a mum. It still scares me, though.”

Trust us, Sienna. The thought of you having kids scares us, too.

According to the UK’s Sunday Mirror, the third time is the charm for Rhys Ifans.

After constantly asking girlfriend Sienna Miller to be his wife - first in August and then at Miller’s 26th birthday party in December - sources say the troubled actress has finally relented.

The couple, who share Sienna’s pad in Notting Hill, are now looking for a home in Oxford and a cottage in Wales.

“Rhys has admitted he and Sienna are getting married,” said an insider. “Everything is supposed to be hushhush, but Rhys is over the moon and finding it hard to keep quiet… he can’t believe she finally said yes.”

Neither can we. But we’d like to wish Rhys Ifans and Sienna Miller the best of luck in their marriage. It’s destined to last for days and days.

Rhys Ifans may be nuttier than Britney Spears.

While seemingly impossible, consider the recent actions of the scarcely known actor: he’s asked for Sienna Miller’s hand in marriage.

According to the UK’s Daily Mail, Ifans “is fed up with all the secrecy around their relationship and wants to make it a permanent thing… he has asked Sienna to marry him and it’s the last time he will ask. He wants everyone to know they are officially an item.”

Wow, an ultimatum. Ifans must have gone to the Hank Steinbrenner school of proposals.

Perhaps proving that she’s learned a lesson from her mess of a relationship with Jude Law, though, Miller is trying to keep things slow and steady.

“Sienna has yet to make a decision and Rhys can’t understand why,” the newspaper’s source said. “Sienna’s always trying to avoid the official relationship topic and is happy to keep it a low-profile affair.”

This is not a Sienna Miller nude photo.

But it actually may be more fun to look at.

Take a look at Miller, coming back from yet another night of partying, ready to blow. And we don’t mean her new man, Rhys Ifans, sitting up front. Although that will probably come later.

For now, we’re just talking some serious chunks.

Kim Porter can relax now.

While celebrity gossip reports had Diddy leaving his babies’ mama for Sienna Miller, it appears as though this promiscuous actress has found a new man instead: Rhys Ifans.

The British actor with the weird name must have even weirder taste in women, as not many of us would go for Jude Law’s sloppy seconds. Especially when we can see Sienna Miller nude without any risk of disease.

But the two look happy below, don’t they? Picking up gardening tools like they were Zanessa or some other normal couple. Good for them!

Sienna Miller is seen here with her new man, Rhys Ifans. Odds are high she’ll be sleeping with Criss Angel soon, however.

Has Diddy seen Sienna Miller nude? That’s the question Kim Porter has wrestled with for months now.

Relaxing here, though, the actress is letting us all stare at her bare body kicking back on the beach. Clothes be damned!

Perhaps Miller was pissed off at The Hollywood Gossip for not including her in our recent Beach Body Photo Finish between Nick Lachey and Brody Jenner. Sorry about that, Sienna.

But if you’re revenge is to sit around showing off your breasts, there’s a good chance we forget about you next time, too.

Help us answer this question, readers: Who is hotter, Sienna Miller naked or Mariah Carey naked?

Hayden Panettiere, step off.

Yes, we know. You’re an up-and-comer, as we’ve seen in some recent photos. But you’ve got nothing on some of the sex-crazed, attention-craving purveyors of girl-on-girl action seen below. Consider this something to strive toward.

Let’s take a look at The Hollywood Gossip’s All-Star Team …

FRIENDS WITH BENEFITS: Lauren Conrad (left) leans in to give Heidi Montag some sugar. And this was before Heidi’s boob job! There will be no more slumber parties or tickle fights between these former roomies, though. Just real fights. LC and Heidi aren’t really friends, mostly because of her relationship with that d!ck Spencer Pratt. The photo at right, of a pre-train wreck Britney Spears going at it with Madonna, needs no introduction.

SISTERS AND PORN STARS: We knew she’d sleep with just about anything, but we didn’t expect to see Sienna Miller (left) gettin’ freaky… with her sister! Yes, borderline incestual girl-on-girl action, ladies and gentlemen. Let’s just hope she didn’t slip her the tongue. And while it’s probably not fair to include a porn star in this feature (as they get paid for lesbian action), we weren’t about to exclude the lusty pride of Broward County, Mary Carey.

BEAUTY QUEENS GONE WILD: Call it (disgraced) beauty queens row. Tara Conner and Katie Blair (left) not only made headlines for winning the 2006 Miss USA and Miss Teen USA pageants, but for hooking up. With each other. Is this a great country or what? Meanwhile, Katie Rees (right, middle) was stripped of Miss Nevada honors after this pic and others like it surfaced. But who are you gonna remember, her or Helen Salas? Exactly.
