Colton Haynes, Shay Mitchell, & Lucy Hale: iHeartRadio Guests!

Colton Haynes hits the red carpet while attending the 2013 iHeartRadio Music Festival on Saturday evening (September 21) at the MGM Grand Garden Arena in Las Vegas, Nev.

The 25-year-old actor was joined at the event by his Arrow co-stars Willa Holland and Emily Bett Rickards, who he posed with on the carpet. He also attended the iHeartRadio Village earlier in the day to present a performance.

Pretty Little Liars ladies Shay Mitchell and Lucy Hale were also in attendance at the music festival. They hit the stage to present Phoenix‘s performance.

FYI: Lucy is wearing Stella & Dot jewelry. Shay is wearing a Ralph and Russo dress, Givenchy shoes, a Jimmy Choo clutch, and a Kimberly McDonald ring. Fun fact: Her dress has real 24 karat gold pieces in it!
