She’s no stranger to massive industry events, and earlier this evening (May 19) Hayden Panettiere paid a visit to the MGM Grand Garden Arena in Sin City for the 2013 Billboard Music Awards.

The “Nashville” star was all about hamming it up for the paparazzi as she hobnobbed with fellow attendees along the way.

Competition for each and every trophy tonight will be fierce, with “Saturday Night Live” alum Tracy Morgan handling the hosting duties.

The top nominees this time around are Taylor Swift, Maroon 5 and fun each with eleven chances at scoring some hardware, while Rihanna received ten nods and Carly Rae Jepsen was nominated in nine different categories.
