Gregg Sulkin And Victoria Justice Brought Their Disney vs. Nickelodeon Beef To 'Lip Sync Battle'

Is it hot in here, or is it just us?

Gregg Sulkin and Victoria Justice may be good friends now, but back in the day, they got their starts on rivaling networks: Disney Channel and Nickelodeon, respectively. So when it came time for them to duke it out on the "Lip Sync Battle" stage, things got especially heated.

The night kicked off with Round 1. Justice's take on Bonnie Tyler’s "Total Eclipse of the Heart" was a total crowd-pleaser, as the former "Victorious" star slithered her way across the stage and into the audience's hearts.

Not to be outdone, Sulkin followed that up with The Darkness' "I Believe in a Thing Called Love," which is kinda the most perfect "Lip Sync Battle" song selection we've seen so far. (Sorry, reigning song queen Julianne Hough.) Thanks to a little bit of stripping (it was just a sweater, but STILL) and an epic song choice, Sulkin matched Justice's performance tit for tat.

And then came Round 2, and that's when things got completely crazy. Justice came out swinging with Nelly's "Hot in Herre," and while the bandaid was a nice touch, it wasn't the kind of bonkers performance we've come to expect in Round 2.

Sulkin, however, got the memo that this was a competition. Once again, his song selection was on point. How can you not smile when you hear Kelis' "Milkshake?!" Add a crazy wig and backup dances on top of that and you have a winner.

Of course, the cherry on top of his amazing performance was definitely strip-tease. The MTV star put it all on the floor when he came out for his second-round song with a wig and let his backup dancers rip off his shirt to reveal a set of impeccable abs. Costumes are a plus on “LSB,” but a shirtless number will always get the applause.

In the end, Sulkin took home the "Lip Sync Battle" championship belt on last night's episode and scored a major W for the Disney Channel. Your move, Nickelodeon.
