Jennifer Lopez Abs: Hot Mama Flaunts Toned Tummy on Night Out After Wardrobe Malfunction

Pop superstar Jennifer Lopez is flashed her toned abs on a night out with her boyfriend Casper Smart.  The 43-year-old showed no sign of aging as she walked with her 25-year-old boyfriend in the streets of London.

Lopez recently suffered a wardrobe malfunction when her nipple was revealed during her concert on stage.  Despite that embarrassing moment, the diva kept delivering a show full of dancing and passion.  

Lopez is the mother of twins Max and Emme whose father is Marc Anthony.  The two divorced last year.  

After they separated, Lopez started a relationship with Smart.  Though they are nearly two decades apart, sources say that they are sincerely in love.

"Jennifer thinks she is very lucky to have met Casper," a source close to Lopez said to People. "He is everything that Marc wasn't: kind, supportive, appreciative...There is a lot of love between [them]. He treats her like a queen."
