Lady Gaga wasn't the only one to gift Kelly Osbourne with a cake for her birthday. Turns out, the star also got a very special one at her top secret birthday bash at Beacher's Madhouse in Hollywood last Saturday.

The extravagant dessert was covered in pictures of the E! star with her famous pals Miley Cyrus and Taylor Swift (who were unable to attend the soiree in person).

Not that the star—who turned 29 on Oct. 27—was without friends for the night. In fact, the exact opposite according to source:

"Surrounded by a big group of friends, Kelly sat in the middle of the club and was treated to an extra special performance by her pal and showman Jeff Beacher," says the eyewitness. "Jeff reenacted an important pop culture moment for Kelly. He had a mini Kim (Kardashian) and Kanye (West) come out onto the stage. Mini Kanye sang a song to mini Kim, and then he got down on one knee and proposed to her. Kelly couldn't stop laughing. It was hysterical. She loved every minute of it."

Afterwards "everyone sang ‘Happy Birthday' to her, she was very touched," the source adds. "She was having an incredible time and stayed right until the end."

Also at the theatre that night were Paris Hilton, sister Nicky Hilton and Dave Chappelle. But it was just Kelly and her friends who got to wash down the yummy cake with festive, specially prepared cocktails by Yacht Club Vodka and Casamigos Tequila.
