Jennifer Lopez's Ex-Hubby -- I'm Not Jealous of Casper Smart, I Support J.Lo!

Cris Judd ain't bitter that his ex-wife Jennifer Lopez found a younger, paler back-up dancer to mess around with ... dude tells TMZ he couldn't be happier for the pop star.

Judd married Lopez back in 2001 ... then divorced in 2002 ... and he's since re-married to a non-famous lady named Kelly A. Wolfe.

Don't hate -- appreciate.
