The cast of Big Brother has made an art form out of sparking romances with fellow houseguests, continuing to prove that love truly knows no bounds — not even being trapped in a house together for 99 days.
While some of the couples that form in the Big Brother house stay there, others have turned into stable marriages and Big Brother babies.
So celebrate the first U.S. season of Celebrity Big Brother, here are some of the most memorable showmances of all time.

Despite not taking home the prize, Nickson still won America’s Favorite Houseguest, and the couple is currently competing together on The Amazing Race season 30.prevnext
