Nadine Coyle Nipple Slip

Nadine Coyle of the British girl group, Girls Aloud, had a nipple slip when she was with her boyfriend, former Desperate Housewives hottie, Jesse Metcalfe (as the gardener of Gabrielle Solis played by Eva Longoria). Nadine Coyle was slated to perform at the 15th birthday party for the G.A.Y. night at London’s Astoria.

Nadine was unaware her dress has slipped down exposing her nipple while Jesse was clinging to a Red Bull can, while being swarmed by paparazzi.

The couple who have been dating for over a year are set to marry next summer in Los Angeles and plan on officially announcing the engagement in an upcoming magazine photoshoot.
