Jilted Jennifer Lopez 'Set to Write Sex Revenge Tracks' Branding Ex-Husband Ben Affleck 'Flop in the Sack'

She's still Jenny From the Block... and Ben Affleck's apparently a flop.

RadarOnline.com can reveal J Lo is said to be planning to hit her estranged husband below the belt with cruel sex revenge by penning slamming songs describing him as a huge flop in the sack.

Sources claimed the furious diva, 55, is determined to smack back at Affleck, 52, who smashed her ego by giving her the boot after just two short years of marriage.

The 55-year-old songbird previously wrote a song praising her bedroom romps with the Oscar winner, but sources alleged she's done a 180 by claiming Affleck turned out to be a major flop in the end.

Sources said: "When things were good between them J Lo put Ben and his bedroom skills on a huge pedestal.

"But her rose-colored glasses are off and she's telling people he was actually a pretty selfish and basic lover."

They continued: "She's annoyed she wrote all those sexy lyrics about him and is now ready to write a follow-up, basically a break up song, that will hit him where it hurts and blast him for all the ways he let her down, including between the sheets."

As RadarOnline.com readers know, the Benifer 2.0 fairytale reunion rapidly reeled into a nightmare after they got hitched, leading to a stormy split this summer when Affleck packed his bags and moved out of their marital home.

Sources claimed he's since been griping to pals about how her notorious control freak ways were too much.

Meanwhile, insiders alleged J Lo has been slamming the father-of-three all over town, raging about his insensitive antics plus the cozy relationship he has with his ex-wife, Jennifer Garner, whom he shares children with – Violet, 18, Fin, 15, and Samuel, 12.

Sources said: "She's very fired up and angry right now.

"Part of the way she's dealing with her emotions is by writing – and her team is encouraging her to channel that into songwriting.

"It's therapeutic for her and she's getting some satisfaction knowing that she's going to eventually get some revenge by humiliating him."

As this outlet reported, J Lo was said to be "extremely hurt and humiliated" by the way her marriage with Affleck soured.

Sources claimed the On the Floor singer not only felt "used" by her estranged husband, but was ready "to get even".

In addition to allegedly penning songs slamming his bedroom skills, spies claimed J Lo wanted to "strike where Ben’s most vulnerable – his bank account" as they geared up for their multi-million dollar divorce.

Insiders added J Lo "made an itemized list of all their expenses and is seeing how she paid for most of everything".
