Mariah Carey wardrobe malfunction, her nip slips out during So So Def anniversary gig

London: Mariah Carey shows off more than just her curves as her nipple slips out of her skimpy strapless dress.

According to the Sun.co.uk report, the voluptuous singer strutted her stuff on stage at an all-star concert in the revealing white frock as she helped celebrate 20 years of hip-hop record label So So Def in Atlanta over the weekend.

Mariah was joined at the event by the likes of Usher, Jay-Z and label founder Jermaine Dupri as they performed to a packed out Fox Theatre in the city on Saturday night.

The 42-year-old Hero singer has previously recorded alongside legendary rapper and producer Jermaine on several tracks including the 2006 Grammy Award winning chart-topper We Belong Together.

And Mariah was more than happy to help close the gig for her friend as she presented him with a huge cake covered in music notes and CDs.

The pint-sized superstar beamed as he accepted the gift from leggy Mariah, flinging his arms around her.

Earlier this month Mariah was seen enjoying a naked bath with her dog as she celebrated Valentine's Day with her husband Nick Cannon.
