Watch: Jennifer Lopez & LL Cool J perform ❝All I Have❞ (Rock & Roll Hall of Fame.)

Jennifer Lopez and LL Cool J performed their hit ❝All I Have❞ at the 
Rock And Roll Hall of Fame induction for the honoree himself!
Adorned in Dolce & Gabbana, Jennifer Lopez performed as part of LL Cool J's big night, which saw the legendary rapper receiving the Award for Musical Excellence.❞ J.Lo and LL Cool J's chemistry is off the richter scale! They should have done more songs together. The performance was solid until she tried hitting those high notes live, and I hollered! She really can't sing and she's so unapologetic about it too. Aint it funny?
