Jessica Biel's marriage vow

Jessica Biel doesn't want to marry Justin Timberlake. The 'I Now Pronounce You Chuck and Larry' actress - who began dating Justin in February shortly after he split from Cameron Diaz - believes marriage is just a piece of "paperwork".

Jessica told Cosmopolitan magazine: "I don't feel the need to settle down right now.

"And if I do meet somebody, I don't feel the need for the paperwork of marriage. For me, a verbal agreement is enough. I don't know if I want to get married."

The 25-year-old actress, who is rumoured to be planning to move in with Justin after his world tour finishes next month, also revealed she hates it when men try and impress her with cheesy chat-up lines.

Jessica, who once starred in hit US TV show '7th Heaven', said: "I don't get approached often. Although I did the other night and it was the worst pick-up line I've ever heard! I was at a concert and this guy came up to me and said, 'I know who you are and I know guys come up and say the worst things to you all the time'. And I'm waiting for the great line and he said, 'Do you remember that one time on '7th Heaven' when you barked like a dog? That was my favourite episode!'

"My friends looked at each other like, 'He totally blew it. He thought we were going to have this moment and he blew it!' "
