Lo a Happy 50th Birthday: 'You Are Simply The Best Partner In Life' "It's your party, Jennifer!" her fiancé captioned a heartwarming video montage on Instagram By Justin Curto Published on July 24, 2019 10:24 AM Share Tweet Pin Email Jennifer Lopez is now 50 and, as always, her fiancé Alex Rodriguez is supportive as ever! The former Yankees star, 43, posted a sweet video montage for Lopez on Instagram for her birthday, pouring his heart out while candid videos of his fiancée play in the background to the tune of Billy Joel’s “This Is The Time.” “Hi baby girl, just want to wish you a happy birthday,” Rodriguez starts the video. “I cannot believe this, baby girl. Since we’ve been together you have made me feel like everyday is my birthday.” “Thank you for your passion, and your energy, and your inspiration, and your endless pursuit to be the best at everything that you do,” he added. “You are simply the best partner in life, the best daughter, the best mother, the best performer. We love you, your fans love you, your children love you and I love you. Let’s make this birthday a very special one.” Alex Rodriguez and Jennifer Lopez with their children.

Alex Rodriguez/Instagram Pop star Lopez is touring behind her birthday on the It’s My Party tour. A-Rod and their four children — Lopez’s twins Maximillian and Emme, 11, (with ex-husband Marc Anthony) and Rodriguez’s daughters Natasha, 14, and Ella, 11 (with ex-wife Cynthia Rodriguez) — showed up at her Madison Square Garden performance earlier this month. When the New York City blackout cut Lopez’s performance short, the four children danced and sang to comfort her. “How great are our kids?” she asked Rodriguez in a video she posted. (She rescheduled the concert for two days after the blackout.) Lopez also stars in the upcoming stripper drama Hustlers, and director Lorene Scafaria told Vulture last week that Rodriguez went with Lopez to a strip club to get “insights” for the movie. The couple got engaged last March, when Rodriguez popped the question on a Bahamas vacation. Lopez told PEOPLE afterward, “We’re really happy.” “We have [an] appreciation for where we are in our lives today, and that’s what we’re enjoying the most,” Rodriguez added.
