Jessica Alba invited her celebrity friends over to her Beverly Hills home to celebrate her eldest daughter Honor Warren's fifth birthday on Saturday. Gwen Stefani and Gavin Rossdale brought along their sons, Kingston and Zuma, while Rodger Berman toted his little one, Skyler, to the bash. Meanwhile, Gwen's No Doubt bandmate Tony Kanal made an appearance at the celebration with his family. Jessica shared a photo of the birthday girl on her Instagram, writing, "Today 5 years ago my sweet little angel Honor came into this world. I'm so blessed to be her mommy." She threw the special event for her little one before she headed off to the 2013 Guys Choice Awards to mingle with stars like Jennifer Aniston, Ben Affleck, and Bradley Cooper. Aside from attending award shows and planning her daughter's big day, Jessica has had a busy week filming Dear Eleanor in Colorado. She headed back to work yesterday evening, posting photos of her airport dinner on her Instagram and snaps of her friend waiting for their luggage.
