Jessica Alba [1] went all out for her 36th birthday. On Friday, the actress and Honest Company founder [2] hosted a "Prince vs. Michael Jackson [3]" dance party at The Peppermint Club in LA, and among the guests were close friends Nicole Richie [4] and Joel Madden [5], Cameron Diaz [6] and Benji Madden, Jaime King, Shay Mitchell, and Beyoncé! The pregnant singer was spotted leaving [7] in an MJ-style black fedora and sparkly coat with BFF Kelly Rowland [8]. Jessica was dolled up in a low-cut black jumpsuit, while her husband, Cash Warren [9], took it one step further in a printed Prince getup [10]. The couple is clearly on a theme party kick, as they threw a pajama bash for Cash's birthday [11] back in January. Scroll through for all the photos from Jessica's star-studded event.
