Olive Cohen is officially the most popular baby in Hollywood!  The baby daughter of Isla Fisher and Sacha Baron Cohen had a slew of celebs at her birthday party over the weekend. 

Jennifer Aniston, Ellen DeGeneres, Portia de Rossi all gathered at the couple's house. They were joined by David Arquette, Jonah Hill and Dustin Hoffman.  Baby Olive turned 1-year-old, hope she remembers what a rager her special day was!

         

Ellen DeGeneres and Portia de Rossi were married at Ellen's Los Angeles home Saturday evening.  The couple who have been dating since 2004 exchanged vows at an intimate ceremony among close friends and family; both Ellen and Portia wore Zac Posen.  Ellen announced their plans to wed during a taping of her talk show following the decision made by by California's Supreme Court that ruled a previous ban on gay marriage to be unconstitutional.

Congratulations to the new couple!

Spending a Sunday afternoon with Ellen is probably a helluva good time, so it's no surprise that she was joined by her girlfriend Portia De Rossi at their friend Courteney Cox's Malibu home yesterday.  Now that gay marriage is legal in California, Ellen says she plans to marry her long time gf Portia...I can only imagine that Ellen will have a serious, throw down, dance party at their reception!

     

After the stars won, lost and ambled down the red carpet, they headed over to the Pacific Design Center for the 16th Annual Elton John AIDS Foundation Oscar Party.  Heidi Klum looked like a hot mama, making a switch between her red dress into silver number.  Ellen must have taken a page out of her friend Heidi's book because she also dressed up in a silver suit, with lovely girlfriend Portia de Rossi by her side.  Sofia Vergara was there, keeping it classy by not completely allowing her boobs to spill out of her dress, gotta have your
