Benji Madden will reportedly make fiancée Cameron Diaz his wife tonight, Monday, Jan. 5, according to Us Weekly.

The website reports that Diaz, 42, and Madden, 35, hosted a rehearsal dinner with a few close family members and friends in attendance at the actress’ Beverly Hills home on Sunday.

According to a source for Us, the meal began around 7:30 p.m and lasted for about three hours.

Entertainment Tonight reports that Cameron’s close friend and Charlie’s Angels co-star Drew Barrymore — who will also serve as a bridesmaid at tonight’s not-so-secret-wedding — threw her friend a bridal shower at her Hollywood Hills home before the rehearsal dinner.

Tonight’s nuptials come after a 7-month whirlwind romance that began in May, after the two were introduced by Madden’s sister-in-law, Nicole Richie. It was very long until news of the actress’ engagement to the Good Charlotte singer broke on Dec. 19.

“Everyone thinks it’s wild, but are so happy for them,” a source told Us at the time of their engagement. “Benji tends to fall in love easily, but this time it’s for real and he landed a great girl. They obviously both make each other incredibly happy, and there’s nothing better than that.”
