Alex Rodriguez and Jennifer Lopez announced their engagement via Instagram over the weekend, and following the sweet news celebrities and fans alike took to social media to wish the couple congratulations. However, not everyone was super stoked for the couple.
Just a day following the news, fellow former New York Yankee player Jose Canseco took to Twitter to accuse A-Rod of cheating on J.Lo with his ex-wife.
“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 tweeted on Sunday evening.
Canseco claims to have been with his ex when A-Rod called her a few months ago. Towards the end of Canseco's Twitter tirade, he proceeded to challenge the baseball player to an MMA fight and tweeted Jennifer his number in case she wants to learn "the truth."
Neither J.Lo or A.Rod have responded to the allegations.
