Jennifer Lopez and Alex Rodriguez's relationship is still going strong despite their engagement announcement being marred by cheating allegations. And according to one of the actress' former co-stars, there is a reason why they just work.

Lopez's "Boy Next Door" co-star Ryan Guzman recently dished on the actress and her former MLB star fiancé while attending the 9-1-1 PaleyFest at the Dolby Theater in Hollywood in March. The 31-year-old actor told Us Weekly that Lopez has found someone who complements her in every way in Rodriguez.

“I think maybe she finally met her match,” he told the outlet. “That’s a power couple right there. It doesn’t get better than that.”

According to Guzman, Lopez and Rodriguez just "fit," and the actress needed someone who could keep up with her.

"I think she definitely needs somebody of a certain level to keep up with her, that’s for sure. She’s a very hard-working person … always on the job … which is what I admire about her. She’s just one of the hardest working people I’ve ever met in my life,” he explained.

And while Guzman isn't sure if he would be invited to Lopez and Rodriguez's wedding, he is sure that their nuptials will involve some "insane" dancing.

Guzman isn't the only one who believes Lopez and Rodriguez are truly meant to be. Her fellow "World of Dance" judge, Ne-Yo, told Us Weekly earlier this year that Lopez is so head over heels that she "floats into the room and there are, like, butterflies and birds and stuff."

Guzman's statements came a few days before British Playboy model Zoe Gregory claimed that Rodriguez has been pursuing her behind his fiancée's back.

Gregory told The Sun that the former athlete sent her led photos and even asked for a threesome with her and her friends before he got engaged with Lopez. She added that Lopez was "amazing" and "doesn't deserve" the way Rodriguez has been cheating on her.

"While getting ready to marry [Jennifer], [Alex] was asking me for sex videos, demanding we hook up and asking me to make arrangements with other girls," the model told the outlet of Rodriguez. "If he is doing this right up until the point he is proposing to her, it is just not fair."
