Jennifer Lopez fired back at the former MLB star who accused her fiancé, Alex Rodriguez, of cheating on her with his ex-wife.
Jose Canseco took to Twitter last month to accuse the former New York Yankees star of cheating on J-Lo with his ex-wife, Jessica.
“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,” Canseco said.
“I was there a few months back with her when he called her on her phone,” he added.
Lopez, who got engaged to Rodriguez earlier this year, appeared on "The Breakfast Club" on Wednesday morning and addressed the rumors.
"I know what the truth is. I know who (Alex) is," she said. "He knows who I am. We're just happy."
Jessica Canseco, the woman Rodriguez was accused of cheating with, also responded to the allegations.
"I have known Alex for many years and haven’t even seen him for over 5. I certainly did not sleep with him. I am friendly with both him and Jennifer," she wrote.
Lopez added that she's not going to let anyone else affect her relationship.
"We're not gonna let other people come out and tell us what our relationship is. I know what our relationship is."
