It's a 90's clash as a Backstreet Boys member dished on pop sensation Britney Spears.

The "Oops! I Did It Again" singer is touring in Las Vegas in Planet Hollywood with stunning live performances, something A.J. McLean from the Backstreet Boys had the pleasure of watching.

In Wednesday's report from Us Weekly, McLean opened up on what it was like watching Spears on stage where it's safe to say he was blown away.

"Her body's back!" he said. "She looks fantastic! Britney's back, man."

"She's doing fantastic, dude," McLean continued. "She was on her A game. She looked good, she sounded good. She was killing it dancing. Britney showed us around. It was just awesome. It's a great show."

Considering that McLean and Spears are good friends, he was glad to help support her as she killed it on stage.

"Britney's show is phenomenal," he said. "She's an old friend. So it was nice to see her up there doing her thing."

Rumor has it that Spears might have another album coming out soon if her new single "Make Me (Oooh)" does well, according to Las Vegas Sun.

"I'm just particular with this record- it's my baby," the pop star said. "I'm proud of the work, and it's very different. It's not what you would think at all. I'm not rushing anything. I would much rather have it be completely how I want it to be. I just want it to be done right so that my fans will truly appreciate it."

Entertainment officials also pointed out how the singer's shows have been doing so well especially with her sultry outfits.

"It's stronger than ever at the box office," the statement reads. "They are the hottest, most colorful, most bejeweled outfits you've ever seen on a Las Vegas stage. If you thought they were sexy before this, then these are overdrive maximum sexy."
