Alex Rodriguez Shares the Sweetest Birthday Tribute For Jennifer Lopez: "I Love You So Much"

Jennifer Lopez celebrated her 51st birthday on Friday and received a special Instagram shout-out from her fiancé, Alex Rodriguez. The 44-year-old former MLB player took to the 'gram to share a sweet tribute video and sing the praises of Jenny from the block. The minute-long reel, which features Dean Martin's "Volare" in the background, includes photos and videos of the couple vacationing, hitting up glitzy events, and attending Jennifer's "It's My Party" tour. The homage also shows throwback interview clips of Jennifer early in her career.

"Happy Birthday, Macha!!!" Alex captioned the post. "Every moment with you is magical. You are the greatest partner, the best mom, the most amazing performer. A role model. A hero. An inspiration. I'm so proud of you. I love you so much!" Jennifer showed her appreciation in the comments section, writing: "Omg!! I love you and feel so blessed today to have you to celebrate with my baby!! ♥️♥️♥️"

The pair started dating in 2017 and got engaged two years later during a getaway in the Bahamas. We can't wait for the duo to officially tie the knot in front of their friends and family, including Jennifer's 12-year-old twins, Emme and Max — whom she shares with ex-husband Marc Anthony — and Alex's daughters, Natasha, 15, and Ella, 12 — whom he shares with ex-wife Cynthia Scurtis. They haven't announced a wedding date yet, but while we wait, look ahead to see more snaps from Jennifer's birthday celebration at home!
