How's that for well connected? Khloe Kardashian got a backstage pass to Jennifer Lopez's first ever concert in her home borough, the Bronx in New York City, thanks to her rapper boyfriend French Montana—and the reality star snapped Instagrams galore with her new famous pals.

PHOTOS: Khloe's style evolution

Kardashian, 29, puckered up with Fat Joe and J.Lo herself in a snap captioned "Bronx Kidddddd" at an afterparty for the State Farm Neighborhood Session gig on Wednesday, June 4, at Pelham Bay Park. She also posed with her boyfriend Montana, who took to the stage with the "First Love" singer earlier that evening, declaring him to be "My rockstar, my only star, my North Star."

The reality TV star wore a very sexy, low-cut crop top, black pencil skirt and pointed black high heel shoes to the outdoor gig. A source at the event told Us Weekly Kim Kardashian's little sister was watching in the wings while her beau performed. "After French's set with J.Lo, security cleared a path so he could come off the stage," the source said. "Khloe was with him and he guided her down and held her hand as they were making their way out with his entourage."

Earlier in the week, Kardashian got some criticism from fans for posting a picture of herself and Montana holding a gun on the set of his new music video for "They Don't Love You No More." The TV star’s mom Kris Jenner has also expressed concerns over her daughter's new romance, sources have told Us previously.

But at Wednesday night's show there was no denying that Montana's gig was the place to be. The 90-minute free concert was Lopez's first ever performance on her home turf. "Don't you just love Bronx summers?" the mom-of-two asked her thousands of fans in the park, adding, "It's a dream come true."

Lopez gave a nod to her former neighborhood by ending the show with her 2002 hit "Jenny From The Block." The singer wowed in a stunning green leotard-style outfit, a throwback to her now infamous, plunging neckline Versace Grammy gown from 2000.
