Cameron Diaz is dating Benji Madden.

The 'Other Woman' actress was first introduced to the Good Charlotte rocker by her ex-boyfriend Justin Timberlake several years ago, but their relationship recently turned romantic after her close pal and his sister-in-law, Nicole Richie, set them up on a date.

A source told UsMagazine.com: ''It's very new. (They're) just hanging out.''

The insider added: ''Nicole thought they'd click.''

The 41-year-old actress was spotted driving around Los Angeles with the 35-year-old musician, who once dated Paris Hilton, last week and she was later seen shopping with a huge smile on her face, according to X17Online.com.

The blonde beauty, who also previously dated Alex Rodriquez and Jared Leto, also took her new beau to a party for her friend Vicky Vlachonis' 'The Body Doesn't Lie' book launch at Gwyneth Paltrow's home on Thursday (15.05.14).

Cameron recently admitted she has had a romantic relationship with a woman in the past and insisted she wasn't actively searching for a man to share her life with.

She said: ''There are many soulmates. My soul has a lot of different facets and it needs a lot of different men. Friends, too. Friends can be soulmates!''
