"One nation, under God, indivisible, with liberty and justice for all," began Lady Gaga's Super Bowl halftime show tonight -- then she dove into Houston's Reliant Stadium. Yes she DOVE in!

Gaga was perched on the edge of the arena, tethered by a harness that would lower her onto the field to begin the performance of her life. Unfortunately, she didn't exactly bring the house down. She did well, it was a solid performance, but it wasn't Beyonce! Sorry, Gaga -- ballads = boring so "Million Reasons" was a little slow. Then, other than that, she sang NO new songs and there was no guest performer!

We love us some Gaga but there was something missing tonight ... liked it, but it was a little flat. She almost redeemed herself with this mic drop and ball catch at the end, though ..
