Sideshow:

Christina Applegate

, 36, who in July was diagnosed with breast cancer, told

Ellen DeGeneres

on Friday that after undergoing two lumpectomies and a double mastectomy, she finally feels huggable again.

"I was afraid of people hugging me. People are really huggy at those things," says the

Samantha Who?

star, referring to the Stand Up To Cancer charity event last month.

"I apologize," said Ellen. "I hugged you." Applegate was in a forgiving mood. "But now I'm good. I'll grab ya," she told Ellen.

Applegate, who says she kept her condition secret for months, says she is now cancer-free.

Katie Holmes

' Broadway premiere in

All My Sons

might not go as smoothly as she had hoped. The New York Daily News says members of the anti-Scientology group Anonymous plan to demonstrate outside the Gerald Schoenfeld Theatre, where the play is to open on Thursday. Katie's hubby,

Tom Cruise

, is a longtime member of the controversial Church of Scientology.

A church rep tells the News that Anonymous is a "terrorist group" that "has fueled religious hatred and intolerance."

Playboy

Hugh Hefner

tells the AP that breaking up with

Holly Madison

, who was like his 908,765th girlfriend, was painful and heartrending.

The 28-year-old Holly, who stars in

The Girls Next Door

with

Kendra Wilkinson

and

Bridget Marquardt

, gave Hef his walking papers when the 82-year-old stud told her he wasn't ready to get married or have kids. (He is still a boy, after all.)

"If Holly says it's over, I guess it's over," says Hef. But his heartache and his tears haven't stopped the men's-lib hero from plotting his next move: "It's now apparent there will be some new faces in my personal life."

A new biography about the Hef has blown the lid off one of the smut peddler's deepest, darkest secrets.

Mr. Playboy: Hugh Hefner and the American Dream

by

Steve Watts

claims that Playboy mag's rabbit mascot has a long history in Hef's life: When he was just a young boy, Hef gave a bunny-themed blanket to a lost puppy that later died. (At least the blankie didn't display a rosebud.)

The New York Post says Swedish pop star

Robyn

, who opened for

Madonna

at a few of her European shows, was treated with disdain by the superstar.

Robyn told a Swedish paper that she and her crew were told "not to approach Madonna, not to speak to Madonna and, above all, no pictures."

Says Robyn, "It's strange that they assume that the first thing you're going to do is run after Madonna and ask for an autograph. My worst nightmare would be to turn into Madonna."

High School Musical

star

Vanessa Hudgens

, 19, has bought her first house - at an age when most of her peers are just buying their first cars. The L.A. Times says that the $2.75 mil Tuscan-style house in Studio City has 6 bedrooms, 61/2 bathrooms, a Pebble Tec pool and spa, waterfalls, and a cabana.

"Botox? I think it's fantastic and also horrible,"

Courtney Cox

tells Marie Claire magazine. "It's not that I haven't tried Botox - but I hated it."

Cox said the product makes it impossible for her to move her facial muscles. "I mean, I'm an actor, I've got to be able to move my face," she said.

But perhaps Cox has another motive for hating the 'tox: Celeb news Web site HollyScoop.com says Cox has developed a line of beauty products for Kinerase, including anti-aging creams.
