Erin Foster couldn’t be happier to have (almost) two moms. The Barely Famous star, 36, shared a photo on Friday from a Halloween bash posing with her father David Foster‘s fiancée Katharine McPhee and her mom Rebecca Dyer.

“Love my two moms ,” Erin captioned the photo of herself with Dyer and McPhee, 34, who got engaged to David Foster this summer. Dyer — Erin and sister Sara Foster‘s mother — was married to David from 1982 to 1986.
