He’s always up to something, and last night (January 23) Darren Criss was spotted at the Old Vic Theatre Company Benefit in New York City.

The “Glee” stud showed up at Gotham Hall looking dapper in a charcoal grey suit teamed with a checkered grey shirt and light grey tie.

Making the transition from television to theater, Darren Criss was spotted performing onstage in his Broadway debut of “How To Succeed in Business Without Really Trying” last night (January 3).

The handsome actor was amazing at the Al Hirschfeld Theatre alongside costars Rose Hemingway and Beau Bridges.

Taking the stage for a deserving cause, Darren Criss performed during the Sing Out, Raise Hope benefit concert in New York City on Saturday (December 17).

With the event taking place at Alice Tully Hall in Lincoln Center, the "Glee" star entertained audience members while helping raise funds for The Trevor Project and the Elizabeth Glaser Pediatric AIDS Foundation.
