Jessica Biel has said she doesn’t think she’ll ever act alongside boyfriend Justin Timberlake because they prefer to keep their relationship private.

The couple began dating in secret at the start of 2007 shortly after Justin split from girlfriend of four years, Cameron Diaz. Jessica & Justin initially denied their romance but confirmed their relationship later in the year. Aside from the odd red carpet appearance, the couple keep their relationship largely out of the limelight - and Jessica told Parade magazine recently that is just how they like it.

She explained: “If it was the right thing, yeah, I would love to co-star with Justin. I just don’t know what the right thing is, though.

“We just hang out at home. You have to have a real life because of the kind of crazy Hollywood stuff that you can get wrapped up in.”

She added that she makes sure it’s not just her low-key relationship with Justin that keeps her grounded: “It’s so important to have hobbies and girlfriends, and not know people that work in Hollywood.

“It keeps you sane. I was playing soccer and I joined a kickball league. That’s way more interesting to me than going to some party.”
