Rumor has it that "Full House" star John Stamos really is Denise Richards' rebound guy.

Mouths were hanging at the star-studded sushi joint Nobu in Malibu recently after John joined Denise at her 35th birthday party.

Soon-to-be ex-wife of Charlie Sheen, Denise Richards has reportedly reunited with her old flame John Stamos, after inviting him to her 35th birthday party. "Full House" Stamos, who split from wife Rebecca Romijn in 2004, dated the former Bond Girl when she was a teenager, and the pair has reportedly remained friends ever since.
