J.Lo wears her sexiest dress ever backstage with Sofia Vergara and Jessica Alba

Jennifer Lopez has plenty of high-profile fans.

It’s nothing new to see the singer perform for thousands of people, but there were some serious A-listers in the crowd at Lopez’s concert on Saturday. She performed at the Zappos Theater at Planet Hollywood Hotel and Casino in Las Vegas, and a number of other stunning stars went to see her perform. Sofia Vergara and Jessica Alba as well as singers Dua Lipa and Becky G were at the Vegas show.

Vergara, Lopez, and Becky G all shared the same picture of the five ladies together at the show. Of course, former New York Yankee and sportscaster Alex Rodriguez is in the photo too — you didn’t think A-Rod would not show up to support his better half, did you?

Vergara, in particular, seemed to enjoy the concert. The Modern Family star posted several more photos from the event, including one of her smiling in awe as Lopez performed.

Excited fans commented on Vergara’s posts, sharing that they were at the same concert. Others pointed out how nice it is to see a group of Latinx people building one another up. “Latinas supporting each other!” one person wrote. “Women supporting women, Latinas supporting Latinas,” another person commented.

Based on Rodriguez’s Instagram story and a fan video uploaded to YouTube, it looks like Selena Gomez was at the show too. The former Yankees star shared a video of Becky G and Gomez dancing to “On the Floor” during the concert. Lopez and Becky G actually go way back — the “El Anillo” singer made a cameo in Becky G’s “Becky From the Block” video, an homage to Lopez’s “Jenny From the Block,” in 2013.

Alba also shared a different photo of the group of ladies after the show, minus Rodriguez. She, Dua, and Vergara are all wearing sparkly black attire to match Lopez’s dress, which might be one of her sexiest looks yet. The singer’s gown has a lot of strategically placed cutouts, and she’s rocking it, as always.

Lopez has four more upcoming Las Vegas shows this week, and it’s possible that more celebrities will be at those shows too. Even celebs can’t resist Lopez’s charm, and it looks like her famous fans had plenty of fun with her this weekend.
