Katy Perry is happily married to Russell Brand ... at least that's what the 27-year-old songstress is Tweeting.

After seeing online reports that she had supposedly filed divorce papers, Perry wrote the following on her Twitter account:

"First I'm pregnant & then I'm divorced. What am I All My Children?! Erica Kane... pshhh. If I had a dollar for every time."

After Katy's recent concert in LA, the couple both got fresh ink by celebrity tattoo artist Bang Bang. The couple already have matching tattoos on their inner bicep.

The "One That Got Away" singer and her British comedian hubby, 36, tied the knot in India in October 2010.

And in flats, no less!

Pete Wentz and his model girlfriend Meagan Camper were spotted strolling on Robertson Blvd in West Hollywood yesterday, and not only is the height difference a non-issue, but neither one of them seemed to mind the attention from photographers. Meagan obviously isn't anywhere near as famous as Pete's ex-wife Ashlee Simpson, but she seems pretty chill every time we take her picture!

But should she be?

Yesterday Katherine Heigl stepped out in Hollywood with a pal, and she appeared very eager to get her spandex-clad booty to the gym. The Grey's Anatomy actress showed off her flat-ironed blonde 'do (which is a welcome change from the mom hair she's been sporting lately), but she was dangerously close to giving us an eyeful of camel toe. You gotta be careful with the dri-fit workout tights -- they're not for everyone!

Yahoo has released its 10th annual Year in Review, and while the new iPhone is the top search result for 2011, celebs like Kim Kardashian, Katy Perry, Jennifer Lopez, Lindsay Lohan and Jennifer Aniston made the top ten list for most-searched celebs on the internet.

Casey Anthony and American Idol also made the cut, along with the earthquake in Japan and the killing of Osama Bin Laden. Yahoo also breaks down search terms into categories, such as "Top-Searched Obsessions", which Charlie Sheen won by a landslide. The top athletes were auto racer Danica Patrick and golfer Tiger Woods, while the most-searched political figures were Sarah Palin followed by President Obama.

NOH8

Miley Cyrus is letting the world know that hate shouldn't be tolerated ... and also that she supports same-sex marriage. The 19-year-old songstress is flashing the peace sign, and a black bra, while posing for the NOH8 campaign.

The campaign, created by photographer Adam Bouska and Jeff Parshley, is a "photographic silent protest in direct response to the passage of Proposition 8." Prop 8 says marriage should be between a man and a woman.

Way to take a stand, Miley!

Lady Gaga always pushes the envelope when it comes to fashion, and at last night's 54th annual Grammy Awards nomination concert, she made raccoon-style eyes fashionable!

The 25-year-old singer, wearing a stunning black bow, off-the-shoulder dress, belted out her hit song "You and I" with country band Sugarland. Gaga scored three nominations ... Album Of The Year and Best Pop Vocal Album for "Born This Way" and Best Pop Solo Performance for "You and I."

Sugarland's Jennifer Nettles and Gaga sounded fabulous together! Watch their performance below.

After Mindy McCready and her 5-year-old son reportedly went missing yesterday, her rep has now confirmed that the troubled country singer is seven months pregnant with twins!

No other details regarding her pregnancy have been released, but McCready did address the rumors that she kidnapped her son Zander, telling Access Hollywood, “I am working with lawyers to try to get all this straightened out. I did not steal my child, as it would be impossible for me to kidnap what already belongs to me! There never was any missing persons report and never an Amber Alert.”

The Department of Children and Families told the Associated Press that a missing persons report was filed in Florida on Tuesday after the singer took her son from her father's house in Cape Coral (McCready's mother reportedly has legal custody of the child, while McCready has visitation privileges). A judge has ordered McCready to return Zander by Thursday, but last night the AP reported that McCready would not be able to bring Zander back to Florida on time due to her pregnancy.

It's finally here! The music video for Justin Bieber's Christmas duet with Mariah Carey, "All I Want For Christmas Is You" has hit the web, and it looks like Mariah didn't want to let the Biebs steal the show, as she nearly upstaged him with her super sexy Santa costume!

Mariah previously released her cover of the same song back in 1994, and we can't think of a better way to re-vamp the tune than to show off her hot post-baby bod and include Justin. The new version appears on Bieber's Christmas album Under the Mistletoe, but it seems like he isn't exactly a pro when it comes to belting out Christmas songs. During an appearance on The Today Show last week, Bieber messed up the lyrics to "Santa Claus is Coming To Town", covering up his blunder by singing the same line several times before dancing around. Looks like he pulled one straight from the book of Ashlee Simpson!
