Jennifer Lopez, Mark Anthony Throw Cartoon-Themed Birthday Bash for Twins

There is no question that Max and Emme -- the twins of Jennifer Lopez and Marc Anthony -- had a birthday bash to remember this year! Last weekend, J. Lo and Anthony turned their Hidden Hills home in California into a cartoon-themed wonderland in celebration of their children who turned three years old on Feb. 22.

According to PEOPLE magazine, the afternoon party took place in the family's backyard, which they tented due to threatened rainstorms in the area. Of the 50 guests in attendance were No Doubt's Gwen Stefani, her rocker husband, Gavin Rossdale and their two sons, Kingston (4 1/2) and Zuma (2 1/2). 'The King of Queens' actress, Leah Remini, also attended the bash, bringing along her 6 1/2 year old daughter, Sofia.

Festive cartoon character balloons decorated the yard, which was complete with moon bouncers, cotton candy machines and of course, a huge birthday cake for little Max and Emme. Upon leaving the party, each of the guests received special gift bags.

On the twins' actual birthday, the proud mama took to her Twitter page to wish her babies a very happy birthday. "It's my coconuts bday 2day!!! HAPPY BDAY my beautiful babies ...you're 3 2day and Mama's SO proud! There are no words 4 how much I love u!!"
