Justin Timberlake says he looked like a ''moron'' during his Nsync days.

The singer and actor started off his career in the boyband - alongside Jc Chasez, Lance Bass, Chris Kirkpatrick and Joey Fatone - but Justin admitted some of their outfits still embarrass him, 12 years after they broke up.

He told Details magazine: ''There were many moments in my teenage years where I succumbed to, um, the weirdness of the group I was in. And in trying to conform--we're marionettes!-- I ended up looking like a moron.''

During his days in NSync Justin often sported a full head of curly hair but admitted these days his preferred style is a shaved head.

He said: ''[I love] A shaved head. It's scary the first time you do it, because you don't know what's under there--you could have some weird knot--but a shaved head is just so easy.''

Justin also likened MTV 'Jersey Shore' star Pauly D's famously gelled hairstyle to ''performance art''.

He said: ''I don't like when I see guys do too much hair gel. I don't mean Pauly D--because that's basically performance art. But when you use enough hair gel that your hair becomes a sculpture--and you wanted it to look that way? It's just weird.''
