Macha y Macho! Alex Rodriguez took to Instagram to wish his fiancee Jennifer Lopez a happy 50th birthday and she's in tears and WE'RE in tears!

This touching video posted by A-Rod this morning features a montage of special moments with his bride-to-be, their families, and them together as a couple. Jen commented how it moved her, writing: "I’m crying....I love our life...I love you so much... thank you my beautiful Macho... ♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️"

Sure, there've been allegations of A-Rod cheating, being slimy -- and J Lo has defended him ... and now we're starting to think she may be right. I mean seriously ... this guy is SWEET! And these two may be absolutely perfect for each other at this phase in their lives. They've got kids the same age, both divorced, A-Rod's retired and J Lo's still killing it on the small screen, big screen and on stage -- so he can let her lead and just be behind her 100%. It's a powerful woman and a man who can handle her strength and we love it!
