Last week, Justin was handsome while attending the Free Arts 2014 Annual Art Auction, which raised over $1,000,000 for free art programs.

“It’s always exciting when you meet someone and you’ve known them for so long, and his art obviously speaks for itself. It’s wonderful, you know. It’s just, it’s fantastic! Both professionally and personally,” Justin recently shared to Us Weekly about his close friend Scott Campbell, who was celebrated at the auction.
