Indulging his inner fashionista, Nick Jonas attended the Evening By Sherri Hill presentation as part of New York Fashion Week 2013 last night (September 9).

The “Who I Am” rocker sat next to "Real Housewife of New York City" LuAnn de Lesseps at Trump Tower and seemed entranced by the beautiful models who paraded past on the catwalk.

In related news, Nick told press that he’s thrilled that his brother Kevin Jonas and sister-in-law Danielle are expecting a baby girl.

Jonas gushed, “I’m very excited. I’m trying to get in the right mind frame. I live right next door to a buybuy Baby, so probably going to hit that place up and see if there's anything good there.”
