Looks like Jennifer Lopez needs to invest in some double-sided tape.

Performing at London's O2 arena on Oct. 22, the singer inadvertently flashed her left breast to an unsuspecting crowd gathered for her Dance Again world tour stop with Enrique Iglesias.

Lopez, who dons the same sequined Zuhair Murad jumpsuit night after night on tour, found that the garment also gave her trouble on Oct. 11. Taking the stage in Bologna, Italy, the mom of twins, 42, again suffered a nip slip mid-show.

2012 has not been kind to Lopez when it comes to fashion. In February, when the singer-actress co-presented the Oscar for Best Costume Design and Best Makeup with Cameron Diaz, many wondered if she had an accidental nip-slip on stage.

"The dress fit perfectly to her every inch," Lopez's stylist, Mariel Haenn, tweeted, denying her client flashed the crowd in her Zuhair Murad plunging gown. "There were cups built in and there's no chance that there were any, how do you say? 'slips.'"

Added Haenn: "While the dress did give the illusion of sheer-ness, joke's on everyone who wishes they saw something! If you thought that dress was hot wait until you see what's next."
