Mariah Carey and Nick Cannon bid big at charity auction

Mariah Carey and her husband Nick Cannon showed off their generous sides last week (ends13May12) by making the biggest bid of the night at a charity auction in New York.

The glamorous couple attended the Opera Gallery in the Big Apple for a benefit event in aid of the Urban Arts Partnership on Friday evening (11May12).

Carey had designed a special pair of shoes, and to ensure the auction raised big donations for the special cause, the couple bid $21,000 for a pair of Project Canvas shoes and a luxury diving watch.

Meanwhile, the Hero hitmaker's design made $2,000 when it went under the hammer and was bought by BET network boss Debra Lee.
