Where was our invite?! This looks FUN!

Lance Bass and his fiancé Michael Turchin were treated to a wild his-and-his bachelor party at The Abbey in West Hollywood, and from the look on his face in this Instagram snap, there were more than a few cheeky surprises in store! The pair were joined by pals including Joey Fatone, Alan Thicke, and Cheri Oteri.

The former 'N SYNC boy bander popped the question to his partner last year, and it was announced yesterday they will marry on TV in a 90-minute E! special Lance Loves Michael: The Lance Bass Wedding, set to air on February 5. The lovebirds will be making history in the process, as this will be the first American television broadcast of a celebrity marriage between two men.

Love is love, and we couldn't be happier for Lance!
