Actor Taylor Lautner says he has to be careful when he meets new female friends.
''I do have to be more careful. I would be lying if I said that I don't guard myself more than I used to, but I don't want to be too guarded," Lautner told Look magazine, reports contactmusic.com.
''If you have so many walls up that you can't even make new friends or find new relationships, that would be a bummer,'' he added.
