Lance Bass Celebrates 40th Birthday

Lance Bass turned 40 on Saturday and his birthday bash guest list was a who’s who of boy bands from the ‘90s and early 2000s.

The celebration, held at Rocco’s WeHo in West Hollywood, was attended by Lance’s husband, Michael Turchin, *NSYNC bandmate JC Chasez, Jeff Timmons from 98 Degrees and O-Town members Erik-Michael Estrada, Trevor Penick, and Jacob Underwood.

Lance and O-Town are currently on the Pop 2000 tour together, along with Aaron Carter.

Lance shared a series of photos from the night on Instagram, writing, "Best. Birthday. EVER!!! @roccosweho was on fire with some of my favorite people on Earth! My friends know how to throw one hell of a party. Thank you!"

The party also reportedly included a Spice Girls singalong and special Stoli Vodka cocktails with names like "Drop the Bass" and "*NSYNCO de Mayo."

Other guests included Ryan Cabrera, Lisa Vanderpump of Vanderpump Rules, Retta and Alison Janney.

Bass was presented with a three-tiered birthday cake by Lady M Cake Boutique, while guests made a champagne toast with Moet and were served finger food.
