Mariah Carey shows off cleavage at event honouring UN Secretary-General

The singer 'stole' the show last night as she attended an event honouring United Nations Secretary General Ban Ki-moon in Los Angeles. Dressed head-to-toe in leather, Mariah donned a pair of skintight black trousers and jacket, which was zipped only halfway to expose her lace bra and ample cleavage.
