The 'Sexy Back' singer says his acting contract made him fall for co-star.
Justin Timberlake has joked that a stipulation in his contract for new movie 'In Time' made him fall in love.
Justin, who split with long-term girlfriend Jessica Biel earlier this year, stars opposite Mamma Mia actress Amanda Seyfried and said he had no choice but to fall for her.
"I have a clause in my contract that says if you put someone as beautiful as Amanda in the movie, I have to fall in love with her," JT explained.
Since his break-up from Jessica, Justin has been linked to actress Mila Kunis and the star of his 'What Goes Around... Comes Around' video Scarlett Johansson.
