The 28-year-old actor was up for Choice TV Actor: Drama, but lost out to Ian Harding from Pretty Little Liars.
“Check out my made to measure jacket for the #teenchoiceawards. Thanks @KEPRebels. So many compliments. I designed it myself!” Lucas tweeted about his jacket for the show.
Also spotted on the carpet was Choice Scene Stealer: Female nominee Eden Sher, wearing a lovely Christian Siriano number.
