Mariah Carey Makes Concert Appearance

On March 1, Mariah Carey made her first concert appearance since giving birth to twins Moroccan and Monroe last April.

The New York show was one of four "Plot Your Escape: Four Concerts, Countless Celebrities, 1 Epic Night" events staged by Caesars Entertainment. The three other concerts took place in Chicago, New Orleans and Los Angeles.

In other news, Mariah's husband, Nick Cannon, revealed to People magazine more details about his recent health problems. Cannon was hospitalized for a serious kidney infection in January and, a few weeks later, was treated for blood clots in his lungs.

The 31-year-old says doctors found an auto-immune disease in his system, which caused the kidney disease. Cannon told People, "I feel blessed to be alive. If it wasn't discovered, I don't know (what would have happened)."
