Machine Gun Kelly, who performed at the event, uploaded a photo of himself with his fiancée, Megan Fox, Rodriguez and a blonde woman, who sported a black dress. "The [goat] came to watch the show last night," the musician captioned a photo of the foursome on his Instagram Story.
As OK! previously reported, Rodriguez strayed from Lopez, as he was caught messaging reality star Madison LeCroy.
"Jennifer didn't want to believe all the rumors about Alex's wandering eye, but the Madison thing was the last straw," a source told OK!. "She's wiser now. Once her trust is broken, she's done."
In January, Page Six reported that Rodriguez was seeing Kathryne “Kat” Padgett, but it was still very casual.
“A-Rod is single and enjoying life,” an inside revealed. “It’s not like she’s his girlfriend. They went to Green Bay and then to Minnesota. She’s not his girlfriend. He is a single dude.”
In the meantime, it seems like the "Let's Get Loud" songstress is happier than ever with Affleck.
"Did you ever imagine your biggest dream could come true?" she wrote in a newsletter about how Affleck proposed. "Saturday night while at my favorite place on earth (in the bubble bath), my beautiful love got on one knee and proposed. I was taken totally off guard and just looked in his eyes smiling and crying at the same time trying hard to get my head around the fact that after 20 years this was happening all over again, I was quite literally speechless and he said, 'is that a yes?' I said YES of course that's a YES."
