A look at the happy couple through the years!
Nicole Richie turned 30 on Wednesday and threw a party at the Beverly Wilshire hotel for some of her closest friends. Mary-Kate and Ashley Olsen, Samantha Ronson, and of course Joel Madden were a few celeb guests in attendance. 

The bash went a little past midnight, and although Joel and Nicole’s little ones were at home, they were a big part of the video montage put together by some of Richie’s closest pals.

“Their life doesn’t stop when it’s my birthday. They have school and ballet and this and that. I was just a mom, which I’m totally happy being,” Nic told the LA Times. “My son just had his birthday, and they just don’t care. They’re birthdayed out! We just had the cake and the song and the whole bit.”

A dance party took place after cake was served, with Ronson getting on the mic and challenging people to go head to head in a dance off.

Sounds like a blast!
