Just 24 hours after making her first on stage performance since undergoing a kidney transplant at the American Music awards in Los Angeles, Selena Gomez stepped out to support a good cause on the other side of the country.

The singer, 25, was in New York City to attend the Breaking Through Gala benefiting the Lupus Research Alliance.

The starlet paired her newly dyed blonde locks with a bright yellow dress gathered at one shoulder and an asymmetrical hem.

Selena wore her long bob swept back into a chignon and added black mascara, a touch of blush and some light pink lip color.
