Ellen DeGeneres and Portia de Rossi are making it official.

Hours after Thursday's landmark ruling by the California Supreme Court striking down a state law banning gay marriage, the 50-year-old daytime host announced during a taping of The Ellen DeGeneres Show that she and the 35-year-old former Ally McBeal star plan to swap vows.

In the episode scheduled to air later today, studio audience members greeted DeGeneres' news with thunderous applause and a standing ovation as De Rossi watched from the sidelines.

The show's publicist was unavailable for comment.

Separately, in an interview with The Advocate Thursday, DeGeneres said she was ready to go bridal.

"I'm thrilled that the California Supreme Court overturned the ban on gay marriage," she told the magazine. "I can't wait to get married. We all deserve the same rights, and I believe that someday...not allowing gays to marry will seem as absurd as not allowing women to vote."

DeGeneres and the Aussie actress have been together for four years.
