Alex Rodriguez proposed to Jennifer Lopez and as we all know by now, she said yes. While everyone was super happy to see the two finally get engaged, there were still some people who were waiting in the shadows, ready to break up their union. One of those people was former baseball player and avid PED user Jose Canseco. Canseco took to Twitter to make the vicious claims that A-Rod was cheating on J-Lo with Canseco's 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"

"I was there a few months back with her when he called her on her phone."

"Alex Rodriguez stop being a piece of shit stop cheating on Jennifer Lopez"

J-Lo is now clapping back at Canseco as she appeared on the Breakfast Club this morning. Speaking to Charlemagne tha God, Lopez discredited Canseco and his claims.

"I mean, it doesn't matter," Lopez said. "I know what the truth is. I know who [Alex] is. He knows who I am. We're just happy. We're not gonna let other people come out and tell us what our relationship is. I know what our relationship is."

Clearly, Canseco is going to need to do more if he wants to break these two apart.
