Married for four years, Giuliana and Bill Rancic are getting much more comfortable sharing secrets of their early days as a couple.
In a new clip from Sunday's episode of their Style reality series, Giuliana & Bill, the Rancics open up to pals about their first dates while on vacation in London.
Over dinner, Bill couldn't help but share fond memories of courting Giuliana, and began to go into detail about their second date before his wife butt in.
"Don't tell them how we slept together!" Giuliana interrupted, leaving the table speechless.
The couple -- married since 2007 -- have chronicled their struggles to conceive their first child on the Style reality series, but say season four is all about having "the year of fun."
"[Having a baby is] always in the back of my mind," Rancic -- who endured a heartbreaking miscarriage last year -- told USA Today. "But we're not actively trying."
Giuliana & Bill airs Sunday at 8 p.m. (EST) on Style.
