Jennifer Lopez slams Jose Canseco amid Alex Rodriguez cheating allegations: 'I know what our relationship is'

Jennifer Lopez on Wednesday defended fiance Alex Rodriguez against allegations from former baseball slugger Jose Canseco that Rodriguez was cheating on Lopez with Canseco’s ex-wife.

Lopez addressed the tweets on “The Breakfast Club” in which Canseco claimed she had “no idea” who Rodriguez really is, according to TMZ Sports.

Lopez, 49, told host Charlamagne Tha God she knows what the truth is and knows who Rodriguez is. She said she and Rodriguez are “just happy.”

“We're not gonna let other people come out and tell us what our relationship is. I know what our relationship is,” Lopez said.

Jessica Canseco spoke out on Jose Canseco’s claims last month to shoot down the rumors.

“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. I am friendly with both him and Jennifer. As for Jose he can keep playing with his Alien friends,” she wrote. “In fact I don’t even get on twitter had to download app again and don’t watch tv and had no idea any of this was going on. Last time I saw Alex he was with Torrie [Wilson] and I brought my boyfriend over for dinner. We are just friends my god.”

Canseco infamously mentioned Rodriguez in his book “Vindicated” – a sequel to his jaw-dropping, tell-all book "Juiced" – claiming he introduced Rodriguez to a steroids distributor and that Rodriguez slept with Jessica at the time.
