Last month, Lance Bass of ‘N SYNC tied the knot with his partner of four years, painter Michael Turchin in a beautiful LA ceremony. But before the nuptials went down, the duo celebrated their love in a perfectly over the top joint bachelor party at The Abbey. With former boy band members in attendance, shirtless dancing until the early morning hours, and The Abbey’s signature food and drink specials, the fête had all the ingredients to make this one of the most memorable parties West Hollywood has seen. Check out the exclusive party photos above. And for more behind the scenes coverage of the happy couple’s marriage, tune into E! on February 5th for the special Lance Loves Michael: The Lance Bass Wedding—the first broadcast of a celebrity wedding between two men!
