Jennifer Lopez Works Out In Sports Bra, Unfazed By Alex Rodriguez Cheating Allegations

Jennifer Lopez has just returned home from vacation with fiancé Alex Rodriguez, but she's already hard at work in the gym.

Lopez was recently spotted leaving a workout session with Rodriguez in Miami, Florida. In Daily Mail's photos, Lopez showed off her toned figure in a black sports bra and leggings with gold sparkling accents. She accessorized with large hoop earrings, dark sunglasses and of course, her multimillion-dollar engagement ring from A-Rod.

The former baseball pro was also spotted walking behind Lopez in all-black workout gear. He donned a black hoodie, matching sweatpants and trainers.

Both Lopez and Rodriguez seemed unfazed by the cheating allegations that surfaced right after getting engaged as they held hands while heading to their car after their workout session.

Over the weekend, Rodriguez announced on Instagram that he popped the big question to Lopez during their getaway to the Bahamas and that the "World of Dance" judge said "yes." A-Rod also shared a close-up photo of the diamond engagement ring he gave Lopez that is estimated to be worth $4.5 million.

But just shortly after announcing their engagement, another former baseball star accused Rodriguez of cheating on Lopez.

Jose Canseco made shocking claims on Twitter that Rodriguez has been sleeping with his ex-wife, Playboy model Jessica Canseco, behind Lopez's back. Canseco even insisted that he was willing to take a polygraph test to show everyone that he was telling the truth.

Jessica Canseco, however, took to Twitter to slam her ex's allegations against Rodriguez. She posted that she hasn't even seen Rodriguez in years and "certainly did not sleep with him."

While Lopez and Rodriguez have not addressed the cheating allegations, a source told Us Weekly that the singer-actress is unfazed by the rumors and believes in her fiancé.

"She's heard the cheating rumors in the past and has never let it bother her," the insider said of Lopez. "She trusts him and his love. They are inseparable and together almost all of the time. Jose Canseco has an ax to grind, but she doesn’t hear the noise."
