Here come the brides! An ecstatic Ellen DeGeneres, 50, and longtime girlfriend Portia de Rossi, 35 (both in custom-made Zac Posen designs), swapped "I do's" during an intimate candlelit ceremony held at their L.A. home on Aug. 16. Getting married "is not something we've ever taken for granted," says de Rossi. "That we get to do this, it means a lot."
