We love a good music festival, especially when it involves hot stars from some of our favorite shows! And we know our girl Nina Dobrev fancies herself a concert fan, but which Vampire Diaries star is going to be presenting at the festivities.

The I Heart Radio Music Festival (September 20-21) takes place at the MGM Grand in Las Vegas this weekend. This incredible festival is hosted by Ryan Seacrest, and features great musical talent like Justin Timberlake, Katy Perry, Muse, Bruno Mars, and more — plus an impressive list of guest presenters that includes Ian Somerhalder!

The Vampire Diaries star will be among several of his peers, including Lucy Hale from Pretty Little Liars and Norman Reedus from The Walking Dead, as well as reality TV icons Khloe Kardashian Odom and Kendall and Kylie Jenner!

Don’t have a ticket? Don’t worry! You can visit iheartradio.yahoo.com to watch the live webcast of the festival, view the event on a PlayStation 3 for free, or tune-in to your favorite Clear Channel radio station to hear a live audio stream.

Or, you can catch Ian on TV when the CW airs the iHeartRadio Music Festival as a two-night primetime special on Monday, Sept. 30 (night one) at 8-10 p.m. EST/PST and Tuesday, Oct. 1 (night two) at 8-10 p.m. EST/PST.
