Jennifer Lopez falls on stage during Vegas Residency performance

Everyone tends to fall for Jennifer Lopez -- just ask A-Rod -- but this weekend was different, 'cause she was actually in Vegas falling for her fans ... and bouncing back gracefully.

While performing on Saturday at her Vegas residency show, Jennifer Lopez took a spill on stage, and landed on her famous booty. She got help from a fan in the front row who helped her get back up.

Here is the video below;

Jennifer Lopez, her famous fans and friends celebrated in her dressing room backstage after the show, where they danced and sang along to music, a source told ET. The 49-year-old’s boyfriend, Alex Rodriguez, was by her side, along with Jessica Alba, Sofia Vergara, Dua Lipa, and Becky G.

Selena Gomez also turned up for the event, a day after stepping out with a mystery man for breakfast and a little shopping in Beverly Hills. The Spring Breakers star was beaming in a photo with Dua Lipa and some friends, and also took a turn on the microphone during the fun.

Other stars like Sarah Michelle Gellar and model Ireland Baldwin took group photos with Lopez. This weekend was the second to the last weekend of Lopez’s residency. Lopez’s final run of shows ends on Sept. 29, and is already completely sold out.
