Diaz: 'There's no shame in being happy'

Cameron Diaz has revealed she thinks there's no "shame in being happy".

In an interview with GQ magazine, the actress said: "I love my life, I don’t have any shame in being happy. You spend so many years in darkness with stuff eating away at you - it’s OK to be happy."

The 35-year-old has been single since splitting with Justin Timberlake in 2007 and admitted it doesn't worry her.

"I could be in a relationship if I wanted to be and felt ready to be, but I’m not," Diaz said. "I haven’t finished doing what I’m doing. When I have, I’m sure you’ll hear about it. But, right now, I’m not done cookin'."

Diaz was recently covered in green slime at the Nickelodeon Kids' Choice Awards and won the "Wannabe" prize for being a celebrity children admire.
