Sean Hayes, star of beloved Will & Grace, gives us just another reason to both miss the show and celebrate our moms. For Mother's Day [1], Sean and his husband, Scott Icenogle, performed a tune explaining all the reasons they "love their mama." The couple often posts videos lip-syncing to Facebook, and this is just another gem [2] from the collection [3]. While this particular video is actually from last year, we can't help but giggle at it all over again — also the song they are lip-syncing [4] is so catchy.
