Jennifer Lopez Is Second To None In Jaw-Dropping Las Vegas Debut

Answering the question: How many bodysuits can one wear during a single performance?

BRB, moving to Las Vegas real quick to see JLo slay your faves. 

Jennifer Lopez launched her Las Vegas residency on Wednesday night at The AXIS at Planet Hollywood Resort & Casino and made sure to leave everything on the floor. The "American Idol" host treated an audience chock full of celebs (we'll get to that later) with a jaw-dropping display of her considerable talents: dancing, singing and looking better than a 22-year-old in a sheer bodysuit. 

Britney Spears has performed her "Piece of Me" show at Planet Hollywood since late 2013. The two will alternate nights until Lopez's show ends in June 2016. 

Lopez performed some of the biggest hits of her career as part of her show, dating all the way back to her breakthrough debut album "On the 6," like "Waiting for Tonight" and "If You Had My Love." The show, titled "Jennifer Lopez: All I Have," was directed by choreographer couple Napoleon and Tabitha D'umo (aka Nappytabs) and featured a live five-piece band and 16 dancers.

Jenny from the Block also had a few tricks up her sleeve, surprising all with duets with Ja Rule ("I'm Real"), Ne-Yo ("All I Have") and Pitbull ("On the Floor").

Celebrities like Justin Bieber, Rebel Wilson, Kelly Osbourne, Cheryl Burke, Derek Hough, Rosie Huntington-Whiteley, Hoda Kotb, Leah Remini, Gina Rodriguez, Nicole Scherzinger, T.I. and Wilmer Valderrama were all in attendance for the sold-out show. 

Wilson looked like she was having the time of her life with buddy Osbourne at the show, making sure to get some facetime with the Biebs. 

Bieber later revealed the note he received from Wilson and Osbourne, asking about his post-show plans. Nothing weird!

Lopez, for one, couldn't be more proud of her Las Vegas debut. 

"It felt great. It felt really great," she told E! News in an interview after the show. "It's a room -- it's a different venue than what I've played before and I wanted to tailor the show to fit in that room, and I think it felt really good. I think people got, 'OK, this is JLo's music and concert, but it's also JLo's Vegas show.' I don't like saying the word 'JLo,' but I know that's what people say!"

"But definitely, [it was] an amazing night," she continued. "We worked really hard on it so people could have a good time and everybody at the end of that concert was on their feet dancing and jumping and singing."

We didn't even go to Vegas and can't stop practicing our "Love Don't Cost a Thing" stomp.
