Alex Rodriguez's old teammate claims he's cheating on Jennifer Lopez with his ex-wife

2019 only seems to be continuing the trend of whirlwind celebrity engagements. Jennifer Lopez and Alex Rodriguez have followed in the footsteps of Priyanka Chopra and Nick Jonas (not to mention Hailey Baldwin and Justin Bieber), and decided to wed after two years of dating.

The pair announced their engagement on social media. "She said yes," Rodriguez captioned a picture of a very large diamond on Lopez's left hand, and the singer shared the same snap to her Instagram, complete with eight heart emojis.

There seems to be trouble in paradise, however. An old Major League Baseball teammate of Rodriguez', Jose Canseco, has alleged that the 43-year-old has been cheating on his now-fiancée with his ex-wife, Jessica Canseco.

The former outfielder tweeted the claims while watching World of Dance - where Lopez is a judge - and said that he would take a lie detector test to prove that he wasn't fabricating the rumours.

"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," his Twitter tirade began.

"I was there a few months back with her when he called her on her phone," Canesco continued. "Alex Rodriguez stop being a piece of sh*t stop cheating on Jennifer Lopez [sic]."

"Alex Rodriguez I challenge you to a boxing match or an MMA match anytime you want."

"I am willing to take a polygraph to prove that what I'm saying about Alex Rodriguez is 100% accurate," he later added.

Naturally, the internet had quite a response to the allegations. "I feel like there might’ve been a kinder way to give her the news," wrote one Twitter user, while another corroborated "Clearly this has nothing to do with kindness and everything to do with retribution."

Rodriguez, a former professional baseball shortstop and third baseman, recently revealed how he proposed to his girlfriend of two years. The couple are currently vacationing in the Bahamas, and Rodriguez used the opportunity to pop the the question. He scattered their luxurious hotel bedroom with long-stemmed red roses and petals for J-Lo to walk down.

This is not the first marriage for both parties. The Get Right singer has previously been married three times, to Ojani Noa, Cris Judd and Marc Anthony, with whom she shares 11-year-old twins, Max and Emme Anthony. She was also previously engaged to Good Will Hunting actor, Ben Affleck.

Rodriguez was married to Cynthia Scurtis between 2002 and 2008, and has two daughters, Ella and Natasha, with her.

As of now, neither Rodriguez nor Lopez have addressed the claims made by Canseco.
