Watch Adam Sandler Sing With Courtney Love, Vanilla Ice, & Gene Simmons At Hollywood’s Randomest Holiday Party

Last night, Adam Sandler and his production company Happy Madison threw their annual holiday party at Burbank, CA’s Pickwick Gardens, and, as usual, a gloriously random hodgepodge of celebrities showed up. Seriously, the guest list for this thing is wild: Tom Morello! Josh Gad! Jon Lovitz! Tiffany! Saginaw Grant! Rick Springfield! David Spade! Taylor Lautner! Joey Fatone! Nick Swardson! Martin Kove from Karate Kid! The list goes on. Sandler and his band always play at these things, and this year, he jammed out and sang with Courtney Love, Vanilla Ice, and Gene Simmons, among others. Watch some clips from the event below.
