Out of all the performances at the 2013 Video Music Awards on Sunday, celebrities were in agreement that Justin Timberlake and *NSYNC owned the show with their joint performance.

At the InTouch Weekly Icons and Idols after-party, the stars spoke to Enstars about the highlight of their night at the VMAs and who killed it on stage. Jersey Shore couple Ronni Ortiz-Magro and Sammi Giancola raved about the *NSYNC reunion performance. Ortiz Magro said it brought back "memories from the past" and explained why he idolizes Timberlake.

"He really put on a performance tonight. He really set the bar to show likewhere he's come since NSYNC and no one's realizes that until now," the reality star said. "I followed him from his *NSYNC days with his 'curly yellow hair' I watched him growing up. "

Commenting on Timberlake's acceptance of the Michael Jackson Vanguard Award, which honors artistry and innovation in music videos, Ortiz-Magro said "Give it to him, he deserves him."

Giancola also loved the performance.

"I loved Justin Timberlake he totally killed it. And *NSYNC coming on, even for the short period that they did, I loved it," she said. "I grew up with *NSYNC so it was really cool to see them perform. It was just cool to hear old *NSYNC songs I grew up with. I had Justin Timberlake posters on my wall. Don't let Ronnie fool you, he was singing *NSYNC on the way here, oh yeah."

Real Housewives of New Jersey star Melissa Gorga said Timberlake "blew the roof off" at the awards show.

Modern Family actress Sarah Hyland said the Timberlake and *NSYNC performance was the highlight of the night.

"I was dancing my ass off the entire time," she said. "I was a huge fan of *NSYNC growing up and I was never able to go to their concerts so this is very childhood-fulfilling for me. I was poor we could not afford concert tickets."

Real Housewives of New Jersey star Melissa Gorga said Timberlake "was phenomeonal and amazing" on stage.

Singer Jason Derulo agreed that Timberlake was great on stage, adding, "he did have 30 minutes. That was like a full-on concert. It was a lot of fun. The audience roared."

"I watched Justin Timberlake growing up, [he was] one of my biggest influences so it was nice seeing him get back into the whole danicng thing," Derulo added. "We've been watching Justin and it's been awesome but we haven't seen the dancing side of him since 2006."

When asked what was the best performance at the VMAs, Nick Cannon called out Timberlake's performance, but said it by default.

"Justin was on stage for like 45 minutes so it kinda forced you to like some part of it," he joked. "Time-wise I'm gonna go with Drake but just overall performance, I'm gonna have to give it to Justin."

Following the show, TImberlake tweeted about his great night.

"I think I just caught my breath... That was an unforgettable night for me. Thank you forever," he wrote. "And thank you to my brother, @jimmyfallon for being there to present that award. It was perfect."

The Take Back the Night singer also uploaded a photo of him celebrating his victory by drinking out of a bottle of champagne.
