Taylor Lautner hasn't experienced love at first sight.

The 'Twilight Saga: Breaking Dawn - Part 2' actor admits he's not sure if he believes in the concept of falling for someone as soon as he meets them, but hasn't ruled it entirely.

Asked if he believes in love at first sight, he said: ''I'm still figuring that one out. I go back and forth on that one. Sometimes I say I do and sometimes I'm not sure. I need a few more years under my belt to fully realise if I believe in that or not.''

Because of his worldwide fame, Taylor - who has previously dated Taylor Swift - admits it's hard not to be too guarded when he meets someone new but tries to be as open as he can.

He told Britain's OK! magazine: ''I'm a total people person. I love meeting new people and making new relationships, so I am definitely open to making friends with girls.

''But I would probably be lying if I said that we don't guard ourselves more than we used to, but you don't want to be too guarded and have too many walls up that you can't make new friends or find new relationships, that would be a bummer.''
