Inside Cameron Diaz's Wedding to Benji Madden

— -- Cameron Diaz and rocker Benji Madden, 35, were married Monday night in a small and surprise ceremony at the couple's home in Los Angeles, a rep for the duo told People magazine.

The two got engaged at the end of last year and decided to tie the knot just a few weeks after! This comes after dating for less than a year.

If Diaz, 42, was getting married, you know the biggest names in Hollywood were going to show to support one of the brightest stars in the world.

The likes of Drew Barrymore, Reese Witherspoon, Gwyneth Paltrow, Joel Madden and Nicole Richie were just some of the celebs who attended the surprise nuptials last night, according to People. The wedding had around 90 guests.

New brother-in-law Joel Madden and Richie's adorable son Sparrow, 5, served as ring bearer for the grand event.

Photos also show a huge white tent set up that served as the venue on Diaz's property, along with Jimmy Fallon's wife and producer Nancy Juvonen showing up with Barrymore's husband Will Kopelman.

Dj Samantha Ronson, actress Toni Collette and Jeffrey Katzenberg were also seen arriving in the late afternoon.

Diaz worked with both Collette and Juvonen on hit movies like "Charlie's Angels" and "In Her Shoes."

Trucks from "Classic Party Rentals" and other vehicles carrying beds of white flowers were also outside Diaz's home. Heat lamps were peppered along her backyard to keep guests warm for the winter ceremony. As the sun set, beautiful lights of soft blues, purples and reds could be seen from overhead.

"We couldn't be happier to begin our new journey together surrounded by our closest family and friends," the couple told People after the event.
