But before show time, MTV News has an exclusive first look at the [article id="1710725"]VMA-nominated singer's appearance[/article] on the season finale, dubbed [article id="1706668"]"Big Time Dreams,"[/article] airing on Nick on July 25 at 8 p.m. ET.
In the sneak peek, he is pictured hanging out with "BTR" actress Ciara Bravo, who plays Katie Knight on the series. And, in another first look, the top hat-wearing heartthrob hangs out with the boy banders, who look to be approving of something by giving Mahone a bunch of thumbs (and fingers) up.
"This episode is a fitting ending to season four," Kendall Schmidt told MTV News in a statement. "We always try to go big, and we worked hard to make a finale that will make a lasting impression."
In addition to Mahone, the special will also feature appearances from Nick Cannon, Alexa Vega, Karmin, Mindless Behavior and Fabio. The episode revolves around the Tween Choice Awards, where the boy banders are nominated and booked to close the show. But before the foursome can take the stage, they uncover an evil plot to brainwash everyone in the audience. So BTR have to take down the bad guys and make sure the show rolls on as scheduled.
It's a big summer for both Mahone and BTR. BTR are currently on the road with Victoria Justice on their Summer Break Tour, which wraps up August 11 in Milwaukee. Back in June, they dropped their latest album, [article id="1709066"]24/Seven[/article].
Meanwhile, Mahone just found out he's up for an Artist to Watch, Presented by Taco Bell Moonman at the 2013 MTV Video Music Awards for his Colin Tilley-directed [article id="1708731"]"What About Love"[/article] video. This year's VMAs are taking place on August 25 live from the Barclays Center in Brooklyn.
