Josh Hartnett Gossip

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!

Josh Hartnett starred in Pearl Harbor, but no pearl necklaces were dispensed on his watch - at least not on tape.

The handsome star is demanding an apology and has slapped a defamation lawsuit against Britain's Daily Mirror for rumors of a sex tape - showcasing alleged "sexual dalliances" in a public area of a London hotel, or so says the paper.

Hartnett called the publication's purported claims: "Not only untrue but a complete fabrication, defamatory and unsubstantiated."

That about covers it.

Josh Hartnett added that the supposed sex tape of him is "complete rubbish. The paper said it was 'rumored' I was caught on CCTV. But how can you have a rumor about a video? It would be on the Internet [by] now."

That didn't stop the Lauren Conrad sex tape rumors from popping in and out of the news for like two years, but point taken, J-Hart.

Yes, ladies man Josh Hartnett again got some action - and with a really young hottie. Milo Ventimiglia would be so proud if he could see this story!

After romancing Scarlett Johansson and Helena Christensen, among others, in recent months, the 29-year-old Hartnett was spotted locking lips with the young and sexy Rihanna, 19, last night at N.Y. City club Pink Elephant.

A source said Hartnett and Rihanna â€" who lunched about three weeks ago in L.A. - met up after her Thursday concert at the Nokia Theatre in Times Square.

Hartnett and Rihanna, who were sipping Dom Perignon and vodka throughout the night, "didn't come together, but left together," the witness adds.

How will Chris Brown react to this? That remains to be seen.

Looks like we may have a hot new couple on our hands. Stay tuned!

Josh Hartnett... Rihanna... Jihanna? Rartnett?

Josh Hartnett (below, center) is apparently ready to audition for The Ninth Gate, a mystery involving a rare book dealer's investigation into the occult and directed Roman Polanski.

Unfortunately, that movie came out in 1999 and starred Johnny Depp (left, right). But who can blame Hartnett for wanting to resemble this talented and eccentric star. From smaller, dynamic roles in films such as the one discussed above to blockbusters like Pirates of the Caribbean, Depp never makes a bad career move.

Or it could be just an amazing coincidence. Regardless, it's certainly worthy of inclusion in our celebrity look-alikes feature.

Maybe Josh, who is still reeling from his breakup with Scarlett Johansson, believes that if he can copy Johnny Depp's signature look, he will have better luck with Natalie Portman. Nah, no way she's gonna let him hit that. Sorry man.

THG NOTE: This is the second celebrity look-alike we've featured using a Johnny Depp character - the first being Edward Scissorhands and John Mayer.

The headline above sums up all we know.

The actress, who we've come to love in Garden State, the Star Wars trilogy and other films, keeps a relatively low profile for a superstar. She's like the anti-Tara Reid. In just about every conceivable way. Which is good. Tara Reid blows.

But anyway. What we're saying is that whenever Natalie Portman does decide to make a public appearance, she steals the spotlight instantly.

Recently, she hit up an Armani fashion show along with other celebs - one of whom she has been linked romantically to of late. That would be Josh Hartnett.

The actor, who once dated Scarlett Johansson before moving on to the lovely Amber Sainsbury, is kind of annoying to us. But he sure is handsome. Time will tell if Natalie, who was dating Jake Gyllenhaal last summer, sees something in Josh that we don't.

We feel sorry for Amber Sainsbury.

The actress is perfectly attractive and maybe sort of talented. But she's no Scarlett Johansson, the woman she looks to be replacing.

On November 19, Australia's Daily Telegraph ran photos of Josh Hartnett, Johannson's ex, at a Sydney airport with a "mystery woman." She's now been identified as Sainsbury, his costar in the upcoming horror-thriller 30 Days of Night.

According to the Telegraph, the pair holed up at a Sydney-area hotel and had brunch two days in a row at local café Forbes & Burton.

Harnett's rep downplayed any romance, saying the actor has been hanging out with "a friend… nothing more."

Of course, that's also what they said about Owen Wilson and Kate Hudson at first.

Sainsbury, to be clear, is NOT the next Abbie Cornish. Johannson and Hartnett have actually been broken up for some time now. "They've just been growing apart for a while, and they had had enough," a friend said.

Had enough, Josh? Maybe you haven't seen these Scarlett Johannsson pictures.

The Venice Film Festival may not receive as much publicity as the Emmy Awards when it comes to celebrity fashion - did you see how gorgeous Katherine Heigl at the latter? - but the stars certainly shine bright in Italy nonetheless.

Let's take a look at some of the hottest.

How old is Diane Lane? Who knows. Who cares. The actress looks as beautiful as ever on her way to attending a showing of her latest flick, Hollywoodland.

Sandra Bullock, meanwhile, isn't typically included among Hollywood's finest - but looks like she's trying to Crash that party. Bullock looks up to Speed on the latest fashion here.

Finally, simple certainly works for Josh Hartnett here. We're not sure if he dressed himself or if ladyfriend, Scarlett Johansson helped - but good job no matter what!

Guess it's getting serious. After two years of dating, Scarlett Johansson and Josh Hartnett have bought a home together.

According to Life & Style magazine, the couple purchased a $6 million loft apartment in the TriBeCa area of New York, but Johansoon and Hartnett want some work doing on it before they move in.

The pair fears, apparently, that neighbors may hear various things and people go bump - and oooh and ahhhh - in the night.

"They asked that we change the design to include extra insulation between the bedrooms of the penthouse and the unit next door," said a source from the real estate company.

Oh yeah. The Gossip follows. It seems as though singing isn't the only vocal talen Johansoon possesses. Oh, and the three-bed condominium has two bathrooms and two balconies.
