BEN BOILING OVER J.LO REVENGE TUNE

Takes her digs in ditty while he keeps trying to move on

- 

POP diva Jennifer Lopez seemed to shade ex-hubby Ben Affleck in a new tune about triumphing over a bitter breakup — and sources say the mopey moviemaker wishes his former wife would give it a rest so that they can both move on from their doomed romance.

“J.Lo’s happy to be singing her truth. She’s totally unapologetic and convinced this will be a launchpad for a whole new musical chapter,” an insider says of the emotional song Wreckage of You.

“If it upsets Ben, then all the better, after the hell he put her through. She hasn’t forgotten the pain, and writing about the experience and setting it to music is helping her.”
