She has just four more shows before her All I Have Las Vegas residency ends after 122 performances.

And on Saturday night Jennifer Lopez welcomed gal pals Selena Gomez, Jessica Alba and Sofia Vergara backstage at Zappos Theater in Planet Hollywood Resort And Casino.

The 49-year-old pop star and actress sizzled in a skin-tight, blue sparkly dress with tantalizing cut outs across her chest, tummy and hips as she posed.

Her beau Alex Rodriguez, a former pro-baseball player, was at the show as always, standing behind his girlfriend of 18 months.

Selena, 26, looked relaxed and happy in a dark blue shiny blouse and light blue silky pants.

The Fetish singer wore very little in the way of make-up as she posed happily after posting a video of herself and Becky G dancing in their seats.

Actress and Honest Company co-founder Jessica Alba, 37,  glammed up in a black dress with black sequins while Modern Family’s Sofia Vergara, 46, also went for black with sequins at the gig.

They weren’t the only celebs at the party.

Pop stars Becky G, 21, and Brit Dua Lipa, 23, were seen mixing and mingling backstage along with actress Sarah Michelle Gellar, 41.

Meanwhile, J-Lo also shared a snap of herself with her pals, captioned:  ‘Fun night w these beauties… @jessicaalba @dualipa @iambeckyg @sofiavergara and @arod he’s a beauty too’ with a heart emoji.

Jessica posted the same picture and captioned it: ‘Awesome show @jlo #vegas,’ alongside a set of fire and queen emojis.

Dua wrote: ‘Perfect night seeing @jlo absolutely SLAY the stage in Vegas!! Thank you for having me.’

J-Lo began her All I Have residency in 2016, and has already performed 122 shows, with just four left before she wraps on September 29.
