On the heels of J.Lo's wild 50th birthday bash last week, the family celebrated another big birthday this weekend.
Alex Rodriguez, Lopez's fiance, turned 44 on Saturday.
For his special day, the singer and her 11-year-old twins, Max and Emme, along with Rodriguez's daughters, Ella, 11, and Natasha, 14, sang "Happy Birthday" to him onstage at her concert in Miami.

"Celebrating you today and everyday my love... you are one of a kind, my hurricane and my calm in the middle of the storm," she wrote.
"Thank you for being such a beautiful light in my life... wishing you the most beautiful birthday ever!!! HAPPY BIRTHDAY 13!!!" she added.
Lopez also made an appearance on ESPN's "Sunday Night Baseball" with Rodriguez's daughters to surprise him with a cake.
The celebration didn't stop there. Lopez shared a heartwarming video featuring moments they've shared as a couple, along with sweet shots with their family.
Rodriquez definitely seemed to enjoy his day. He posted a hilarious video of the madness -- and singalongs -- that ensued at his birthday bash.
"I am so incredibly fortunate and grateful for where I am in my life," he wrote in the caption of his post. "I thank the good Lord for my blessings, today and every day."
If their upcoming wedding is anything like these celebrations, we can't wait.
