Alex Rodriguez knows hard work when he sees it – especially when it comes from a significant other.

While gushing about his girlfriend, the former Yankees player called out J.Lo for her amazing work ethnic and ability to keep everything in check. "She’s the hardest working … She’s got like 10 jobs," he told ABC Nightline.

A-Rod isn't too far off with that description. The singer does have endless responsibilities: performing at her Las Vegas residency, starring in TV show "Shades of Blue," producing and co-hosting "World of Dance," raising money for Puerto Rico, recording music, and much more. Oh yeah, and caring for her children and sleeping (once in a while).

"She's a great mother, great daughter, great friend. She's just someone that... she's fun to be around."

The two stars have mixed and mingled their families, who seem to be getting along and adjusting to the new relationship just perfectly. 

Recently, Rodriguez dished on just how good his relationship with Lopez feels.

"... This is the first relationship I’ve been where I feel like we really make each other better. We compliment each other, and there’s really pure, true love," he said. "Just wanting to support the other person and make them happy. So there’s a different selflessness in the love that’s beautiful and different. And healthy!"

AWWWW!
