Jessica Alba Honor

Girls just wanna have fun!

Mom on the go Jessica Alba and daughters Haven and Honor Marie hit the park in Beverly Hills on Sunday -- and it looked like these gals were having some fun!

For a day at the park, Jessica hide her tresses under a wide-brimmed hat, white v-neck, oversized sweater and jeans. The 32-year-old jazzed up her off-duty ensemble with some Tory Burch Noah sneakers. Even at the park Jessica looks fab!

On today's Ellen Degeneres show, the actress told Ellen about a recent birthday party for her husband Cash Warren that wound up getting wilder than planned. Check out the video to hear about how the cops came to the slumber party bash!
