Madonna Super Bowl Halftime Performance: Stars React on Twitter

Last night, Madonna put on quite the halftime show at the Super Bowl. The songstress, who is on the brink of dropping her 12th studio album 'MDNA,' not only performed a slew of hits, but she also collaborated onstage with a bunch of fellow pop stars.

Kicking off her set dressed like an ancient Roman warrior, Madge treated fans to a solo performance of 'Vogue' on a crazy illuminated stage. She was later seen shuffling with party rockers LMFAO, performing her new song 'Give Me All Your Luvin'' with Nicki Minaj and M.I.A., and closing the show with a bang with 'Like a Prayer,' which she performed alongside Cee Lo Green. Pop artists were all over Twitter writing about Madonna's performance -- check out some of their thoughts below!
