KELLY & MARK, 16 YEARS
When Consuelos, 41, joined the cast of All My Children in 1995 to play the on-screen lover of Ripa, 42, their connection was so undeniable, it led them to elope in Las Vegas a year later. And after 16 years of wedded bliss and three children together, their bond remains steadfast. "I think about my husband in the middle of the day because I love him and I can't wait to see him," Ripa told Good Housekeeping in 2010. "He is my best friend. Nobody knows me the way he knows me. We've seen each other in an Avatar, 'I see you' way."
