George Clooney and Julianna Margulies

Former ER lovers George Clooney and Julianna Margulies are still crazy for each other after all these years – as pals, that is.

The actors – who played the dashing Dr. Doug Ross and his onscreen love, nurse Carol Hathaway – recently reunited for the medical drama’s final season.

“It’s been nine years and it was like we’d never been apart,” Margulies told eyebrow guru Ramy Gafni, who recently tended to her famous brows at his RamySpa in Manhattan.

John Mayer shimmies for Ellen DeGeneres

While Jennifer Aniston went into coy mode when Ellen DeGeneres pressed her on the topic of John Mayer, the five-time Grammy winner himself was only too happy to discuss life and times with Aniston, in an interview to air Monday on The Ellen DeGeneres Show.

And neither he nor DeGeneres was particularly shy about certain private details.

“Do you sleep over?” the TV host asks bluntly.

Paris Hilton

Paris Hilton says she sometimes acts dumb on television to get laughs, but in real life she’s “a strong person” who’s been through a lot.

Appearing on the British morning show GMTV to launch her new reality show Paris Hilton’s British Best Friend, Hilton, 27, said she cultivated her dumb blonde image for her hit FOX reality show The Simple Life, costarring Nicole Richie, and it became her schtick.

George Clooney

George Clooney has agreed to come back to the show that launched his career: ER.

Sources close to the series, tells us that ER co-creator John Wells has ordered a closed set to keep Clooney’s appearance under wraps.

It’s not known how many episodes will feature Clooney as the show films its final season. Neither NBC nor Warner Bros. reps would comment, nor did Clooney’s publicist.

Clooney, himself, denied reports last March he was returning.

Having tiptoed around who would make the right guy – or even who is the guy she is now seeing – Anne Hathaway has now been cornered by Ellen DeGeneres on the subject of Mr. Right.

“If you need someone, I will find you a boyfriend,” the TV host tells the Bride Wars star on the Ellen DeGeneres Show to air Thursday. “I’m really good at it.”

Kendra Wilkinson

Bridget Marquardt may have lived in the Playboy Mansion with Kendra Wilkinson, but she hardly recognizes her former housemate – and The Girls Next Door castmate – anymore. And that’s not a bad thing.

“She’s doing amazing, she’s so in love,” Marquardt, 35, said of Wilkinson, 23, who recently became engaged to NFL player Hank Baskett. “She’s changed so much. She’s not even the same person. I mean, she is the same, but she’s different. I love the old Kendra and I love the new Kendra.”

Lo Bosworth and Heidi

Lauren “Lo” Bosworth says she was surprised to learn that her Hills costars Heidi Montag and Spencer Pratt tied the knot while in Mexico away from family and friends — and after a night of tequila and champagne.

“I always thought they were going to get married,” Bosworth said on The Hills: Live After the Show on Monday. “I just didn’t know when. I thought she always wanted a big, beautiful event wedding in L.A. I was surprised it turned out the way it did actually.”

Mariah Carey and Ellen toast

Is Mariah Carey pregnant? No way, the singer insists on Wednesday’s episode of Ellen.

But DeGeneres seemed determined to put her to the test.

“Let’s just toast with Champagne,” the sly talk show host suggested, reaching for a bottle and some flutes.

“It’s just fattening,” demurred Carey – who married Nick Cannon in May – adding, “This is peer pressure!”

When DeGeneres persisted, the two clinked glasses – but Carey only pretended to drink the wine.
