Carly Rae Jepsen Wears Sheer Gown, Grows Up At AmFar Gala (PHOTOS)

Is that really you, Carly Rae Jepsen?

We barely recognized the "Call Me Maybe" singer when she wore a sexy sheer gown to the amFar Gala in New York on Thursday.

Taking on the likes of A-Listers Uma Thurman, Liza Minelli and Jennifer Lopez, the little Canadian Who Could rocked a surprisingly mature Carlie Wong gown which showed off the 27-year-old's fab legs and highlighted her svelte frame with a tight bodice and dramatic train.

Despite the cutie's grown-up look, Carly still wore her signature bangs. (Maybe it's time for a new haircut though?)

After the red carpet, the singer swapped her gown for a slim-fitting blue suit for her performance where we're sure she powered through her hits.

So when's that new single coming out, Carly? We need a new summer hit!
