Think Dr. Phil McGraw never gets weepy? Get real! The blunt doc got a bit blubbery as his son Jay, 26, exchanged self-written vows with Playboy model Erica Dahm, 28, before 70 guests at the McGraws' Beverly Hills home Aug. 12. Turns out tears run in the family: When the groom—who met Dahm in '04 on the reality show Renovate My Family—first saw his bride, "It choked me up and took my breath away," he says. Later, at the reception for 400 guests at the Beverly Hills Hotel, McGraw's brother Jordan unveiled his gift: A surprise performance by Babyface. "It was a Cinderella moment," says Dahm, "and Jay's my Prince Charming."
