Jeff Nichols may have lost the title of Biggest Loser by one pound, but he gained a roommate, co-worker and girlfriend: fellow contestant Francelina Morillo.
"We literally spend 23 hours a day together," Nichols tells PEOPLE. "When one of us has to go out of town you would probably be disgusted with how much time we spend on the phone with each other. She really is my other half."
Nichols and Murillo began dating at the beginning of the year, moved in together in Chicago this past March and now work together for Biggest Loser RunWalk, a race series designed to challenge Americans into getting fit.
"There is no other couple who could spend this much time together and not kill each other," says Morillo. "Over this past year we have realized we are best friends and truly blessed to have each other."
