Even though Jennifer Lopez and Alex Rodriguez may be one of the hottest celebrity couples right now, they’re not exempt from the issues that plague normal, everyday couples. Sources revealed to In Touch that A-Rod cheated on J.Lo and he is currently doing everything he can to make it up to her and earn her trust back.

Jen, 48, is questioning her relationship after she recently found out that Alex, 42, is still in contact with his former fling, fitness model Lauren Hunter — months after Lauren revealed that the former New York Yankee has been sexting her while he was with J.Lo.

“Someone went to Jennifer with new details that Alex was still texting with Lauren, and that’s what made Jennifer lose it,” the insider revealed to In Touch. “Of course, he said it wasn’t physical, and maybe it wasn’t, but in Jennifer’s book, that’s still cheating. They were head-over-heels in love, planning to get engaged. Now Alex’s actions have jeopardized everything.”

And the tension in their relationship has seemingly started to play out on social media. On Jan. 24, the “Us” singer shared a photo of a large bouquet of flowers that Alex sent to her, and that same day Alex shared a quote with a cryptic message. “There’s nothing wrong with making a mistake, what’s wrong is not making the effort to make it right,” the quote read.

The next day, J.Lo shared a selfie and wrote a cryptic message in the caption that read, “It’s all in God’s hands always…#letgoandletgod,” and the insider said, “That was aimed directly at Alex.”

But even though it seems like Jen was willing to forgive Alex, sources say that the damage still runs deep, especially because she’s had three failed marriages in the past. “[Jen] was heartbroken to hear that Alex was talking to Lauren,” said the insider. “Even though they didn’t meet in person, Jennifer considered it a betrayal. Now she has friends and family watching out for her best interests, which means checking in and asking about Alex’s antics.”
