The former Victorious star is co-hosting the event with wrestler and actor John Cena, and Timberlake will be honoured with the Decade Award.
Justice is hoping to get a little quality time with the singer so she can recreate a photo taken when she was 12 and just starting out.
Now 23, she tells WWD.com, "I'd love to meet Justin Timberlake and get a picture with him.
"I met him when I was, like, 12 or 13 at the Shrek premiere. I asked to take a picture with him and his publicist was like, 'No', but he saw me ask and was like, 'No, no, it's OK, I'll do it'. It would be cool to get another one so many years later."
The actress and singer, who will star in the upcoming The Rocky Horror Picture Show TV remake in October (16), is also looking forward to meeting the newly-announced Teen Choice Awards' very special guest Jason DeRulo, confessing she's a "big fan".
