No one's ever cheated on Taylor Lautner
"I've never been involved in any of those situations," the Twilight Saga: Breaking Dawn – Part 2
star says in the December issue of Cosmopolitan
But when it comes to reconnecting with an ex (ahem, Kristen Stewart
and Robert Pattinson
), "I absolutely think it's possible," he tells the magazine. "If it was a long, serious relationship, I think it's quite easy to rekindle. I guess it depends on what damage has been done."
"There's no ex out there who I'm not friends with today," he continues, "and I'm extremely thankful for that."
What does it take to have a successful relationship with Lautner, 20? "Honesty and loyalty are key," he says of his crucial qualities.
"I like to think of myself as very loyal," he says, "and I love everyone I surround myself with, whether they’re friends or girlfriends or whatever."
Of his costar and friend who's been closely watched
