Bitter Bass slams Justin for leaving 'N Sync

Former 'N Sync star Lance Bass felt "completely betrayed" when Justin Timberlake announced he was leaving the boyband in 2004.

Speaking about the band's split for the first time in his new autobiography, Bass admits he was angry that Timberlake waited two years after the group went on hiatus in 2002 to reveal his news.

In the upcoming 'Out Of Sync', Bass reveals Timberlake blamed the group's break-up on his four bandmates - suggesting they were interested in other ventures.

Bass writes: "He didn't think any of us was operating in the best interest of the band. I asked him what he meant by that, and he said: 'Well, you know, when y'all did your movie', meaning Joey (Fatone) and me (and their 2001 film 'On The Line')…

"I couldn't believe it. That sounded like the lamest excuse imaginable. Joey and I looked at each other in amazement.

"According to Justin the whole reason for the break-up of 'N Sync was everyone else's fault? That was crazy! All of us had done nothing but wait around for him to feel he was ready to start work on a new 'N Sync album.

"And hadn't Justin made a movie (2000's 'Model Behaviour') the year before we did ours?...

"I felt completely betrayed… It p**sed me off that Justin's life got set up perfectly before he came back to the rest of us… Justin's time to become a solo star had arrived."

Bass also blames the failure of Timberlake's romance with Britney Spears on the star's ambition.

Bass claims Timberlake, who dated Spears for four years, was too focused on his career to make time for a committed relationship.

Bass writes: "At the time, she struck me as an adorable little teenage girl at a perennial slumber party - staying up late and having a lot of fun.

"She showed no signs of the turmoil she would eventually encounter, maybe because she was so in love with Justin she thought it was going to last forever. I knew it wouldn't.

"Justin already had a great love in his life - his career. He wanted to be a star, and no girl, no matter how great, was going to be able to distract him from that for more than a night or two between trips to the centre of the spotlight."
