Jenny from the Block's Las Vegas show on May 22 could have had more star power than that awards show happening just down the street. In the process, it proved that the entertainment world is just as obsessed with J.Lo as the rest of us are.

On Sunday, just after the Billboard Music Awards had ended, some of the biggest names in the entertainment world shunned afterparties, opting to party with Jennifer Lopez at her "All I Have" show at Planet Hollywood.

Since the show began in January, it has been a celebrity magnet, and that was no more evident than on May 22. Talk about serious star power!

After presenting Justin Bieber with his award for Top Male Artist, Jessica Alba headed down the famous Las Vegas strip to take in the "Waiting For Tonight" singer's show.

"#AllIHave -If you know what's good for you ladies n gents go see @jlo in #lasvegas," Jessica Alba captioned a video of J.Lo performing "I'm Real." "The show is Amazing #dancedthewholetime #sheseverything #pioneer #femalepower -I love her."

She posted another video in which she said, "She's literally #everything."

Seated nearby was Laverne Cox, who also marveled at the singer, saying J.Lo is "life altering." She also said J. Lo is "slaying beyond imagination."

Of the four videos the actress posted, one included Meghan Trainor, who was also on hand.

Khloe Kardashian posted a photo from backstage with J.Lo and several of the celebrities in attendance, including sister Kourtney Kardashian.

"Bow down to the queen," she said.

It seems as though you couldn't spin around and not see a famous face in the crowd on Sunday.

Also in attendance were Ashton Kutcher and Mila Kunis, Demi Lovato and boyfriend Wilmer Valderrama, Ryan Guzman, Malika and Khadijah Haqq, Alex Pettyfer, and LA Reid.

How did J.Lo feel afterward? "Amazing," she told Laverne.

The entertainment world continues to be amazed and obsessed with J.Lo, too.
