*For some reason – maybe because she has a new album out – Mariah Carey decided to take the NYC subway to a charity event where she was being honored.

Dressed in a glitzy light blue gown with dark sunglasses, Carey posted photos of her Thursday, May 29 train ride to New York’s Fresh Air Fund Gala

In one of the pics, she is seen with producer Jermaine Dupri and Stephen Hill, the president of music programming and specials at BET Networks.

“I figured since I’m underdressed, we might as well just take the subway,” said Carey, who was honored during the Fresh Air Fund event.

Meanwhile, Carey is heading for her 17th top 10 album on the Billboard 200 chart with “Me. I Am Mariah… The Elusive Chanteuse.” The set was released on May 27 by Def Jam Records.
