On Dec. 12, the "Love Don't Cost a Thing" singer shared a video to Instagram from her mom's birthday celebration, which was a small dinner party with lots of balloons. Jennifer and her fiancé, baseball legend Alex Rodriguez, helped surprise Guadalupe, who looked over the moon to be honored.
"Surprise," Jennifer wrote in the caption of the video. "Happy 75th birthday to my beautiful mommy!!! I love you so much. We all do. You are the definition of being youthful and timeless at every age ... thank you for your endless love, energy, support and for just being you!!! I love you forever."
In addition to having cake and balloons, J.Lo surprised her mom by inviting other family members to call into the event via Zoom. That's how Jennifer's twins who she shares with ex-husband Marc Anthony, 12 year old Emme and Max, were able to deliver a sweet birthday message to their grandma.
Over video chat, the twins said, "Love you grandma, happy birthday!"
Alex also shared a birthday message to his future mother-in-law. The athlete wrote on Instagram, "What an honor it was to surprise and celebrate @jlo's mother, Lupe, on her 75th birthday. It's obvious where Jen gets her beauty! Happy 75th to a truly wonderful woman."
Jennifer first introduced Alex to her mom in 2017, and photographers captured the trio walking around New York City together during their first group hangout. Now, it seems that Alex is part of the family, which very likely means many more Guadalupe celebrations to come!
