Jennifer Lopez doesn't believe Alex Rodriguez cheated on her

Jennifer Lopez is standing by her man.

The superstar sat down Thursday with The Breakfast Club at New York radio station Power 105.1 to promote her new music.

Of course, talk turned to her engagement with baseball great Alex Rodriguez.

Host Charlamagne tha God noted that shortly after the pair got engaged last month, they had a "hater" in former baseball player Jose Canseco.

Canseco tweeted three days after the engagement was announced: "Watching World of Dance watching J.Lo text Alex Rodriguez little does she know that he is cheating on her with my ex-wife Jessica poor girl she has no idea who he really is."

Lopez laughed it off to "The Breakfast Club" crew.

"I know what the truth is. I know who (Alex) is," she said. "He knows who I am. We're just happy."

Canseco's ex-wife, Jessica, has also responded, tweeting last month: "Those false accusations Jose is making are not true!"

"I have known Alex for many years and haven't even seen him for over 5. I certainly did not sleep with him," she said. "I am friendly with both him and Jennifer. As for Jose he can keep playing with his Alien friends."

Lopez and Rodriguez's love story has been playing out on social media, where the pair appear inseparable.

Lopez ended her interview Wednesday by further defending her relationship with Rodriguez.

"We're not gonna let like other people come out and tell us what our relationship is," she said. "I know what our relationship is."
