We've lined up laser detail shoppers from Jane Norman, New Look and MICHAEL Michael Kors, with prices starting at a bargainous £15.
'There is a lot of security and they are trying to keep the wedding hush-hush by telling neighbours that Cameron is having a pre-Golden Globes party tonight,' a source told People early on Monday morning.
They dated for nine months before breaking up due to Benji being overprotective and not getting along with her friends.
Benji was romantically linked former Playboy Playmate and Girls Next Door reality star Holly Madison.
According to her pal Selma Blair, the actress, 45, has said she is 'done' with the film industry and has no plans to return the big screen.
Speaking at the Oscar's Vanity Fair pre-party in LA last week, Selma, who stars in the 2002 movie The Sweetest Thing with the blonde beauty, said: 'I had lunch with Cameron the other day, we were reminiscing about the film.
She is one of Hollywood's leading ladies, with blockbusters such as Charlie's Angels, Shrek and There's Something About Mary to her name.
But Cameron Diaz has reportedly retired from acting to focus on family life with her musician husband Benji Madden, 39.
