Though Fox walked the red carpet in a sleek David Koma gown, she switched to a sparkling gold dress and silver tiara for her own party. Kelly stayed in his Dolce & Gabbana suit, accented with a manicure that featured $30,000 worth of diamonds.
Earlier that evening, Kelly told ET's Cassie DiLaura he'd be turning the jewels into rings and donating the proceeds to a Cleveland charity.
The couple also said they were headed into the desert once the party ended on Sunday to watch the lunar eclipse and celebrate Fox’s big day -- she said a few days earlier that she always asks to be away from cell phones on her birthday.
"Whatever we do, wherever we go, I just want there to be no phones," she said. The eclipse was sure to make it all the more special. "I'm sure I will be crying a lot,” she said.
