Jennifer Lopez gives Ja Rule an eyeful during ❝Global Citizen Live❞ rehearsals in NYC...

In photos that will have Ben Affleck seething, Ja Rule was caught checking out the very famous derriere of Jennifer Lopez as they rehearsed their 20-year-old smash hit 'Aint It Funny' for 'Global Citizen Live.' Jen likes to shake it as usual, and the rapper continues to admire just like he does for another female artist that Jen often likes to lip-sync to.

Aint it funny? In related news, Chloe x Halle, Doja Cat, Lizzo, and 70 other artists are set to perform at the live event later on, which will take place across 15 different countries and will be broadcasted today in support of Global Citizen’s “Recovery Plan.” Will you be watching?
