Good Charlotte guitarist Benji Madden and Cameron Diaz are getting married

Good Charlotte’s Benji Madden (also of the Madden Brothers fame) is officially tying the knot with actress Cameron Diaz tonight. According to US Weekly, Madden, 35, and Diaz, 42, began dating in May of last year after they were hooked together by Madden's sister-in-law, Nicole Richie. The Good Charlotte member popped the question a few weeks ago in December, six days before Christmas.

The couple were reportedly at a dinner rehearsal yesterday, January 4, in Beverly Hills. 

While Good Charlotte remained fairly silent in 2014, Benji managed to stay busy with a new project alongside his brother Joel. The duo, operating under the fitting moniker, the Madden Brothers, released their debut studio album, Greetings From California, this past September.

AP sends its congratulations to the soon-to-be newly wedded couple.
