Stars Congratulate Ellen Degeneres and Portia De Rossi

Stars including Katherine Heigl, America Ferrera and T.R. Knight have all offered their congratulations to newlyweds Ellen Degeneres and Portia De Rossi.

The talk show queen, 50, wed her longtime girlfriend, 35, in an intimate ceremony in the backyard of their Beverly Hills home on Saturday, August 16.

Just 19 guests watched as the couple read aloud their handwritten vows, including DeGeneres' mother Betty and de Rossi's mother Margaret Rogers, who flew in from her native Australia for the occasion.

And Heigl was quick to congratulate the couple, telling People.com, "I wish her all the best, all the happiness, all the joy that comes with that certificate in hand."

While Ugly Betty star Ferrera adds, "I'm just so happy that they get to love each other in such an official way."

California lifted its ban on gay weddings in May (08) after the state's Supreme Court ruled the prohibition of same-sex unions was unconstitutional.

And gay Grey's Anatomy actor T.R. Knight is delighted that the nuptials were allowed to go ahead. He says, "I'm happy that they're happy. I'm happy that they're allowed to get married."
