Jennifer Lopez just couldn’t keep it in during Wednesday’s episode of Fox’s American Idol, accidentally dropping an F-bomb that had to be bleeped out.

She blurted it out when co-judge Harry Connick Jr. wouldn’t stop teasing her and once it came out, she immediately regretted it. The “I Luh Ya Papi” singer, 44, grabbed her mouth in shock after she said it.

Lopez was giving her critique of contestant Jena Iren’s performance of Evanescense’s
“Bring Me To Life” when she did a hair flip to demonstrate the performance. "You were kind of fixing your hair, and right at the beginning you kind of just threw yourself into the crowd and your hair went crazy. I wish it would have been more messy,” she told Malone.

Connick Jr. then interrupted and said, “Do that again! I feel another hair flip coming on!” TheWrap reports.

He then started the chant “Hair flip! Hair flip!” and Lopez then dropped the F-bomb but quickly covered her mouth in shock at what she had just done. “That's Jenny From The Block!” Connick proclaimed.
