Alex Rodriguez's daughters Natasha and Ella are all grown up!

Jennifer and Alex began their romance more than two years ago and ever since they’ve become one of the most famous couples in the entertainment industry. Aside from that, the pair have become an inspiration as they have formed their own family despite having kids from previous relationships.

Natasha “Tashi,” 15 and Ella, 11 have a great connection with JLo and they’ve become inseparable since day one. In fact, for the singer’s 50th birthday, Alex’s daughters and Emme, performed a song from Annie as a gift to the Hustlers actress.

The mom-of-two has built a strong relationship with A-Rod’s daughters, loving them as if they were her own. Jennifer recently shared her beautiful thoughts about the pro-athlete’s eldest daughter, who turned 15. “Wishing my favorite teenager a very happy 15th birthday!!! May you forever keep illuminating the people around you with your infectious light. I love you and hope you have the best day,” she wrote on her social media.

Alex can hardly contain how much his little girl is all grown up after starting her freshman year of high school. Just as JLo did, Alex dedicated a special message to his daughter in which he showed his emotions for his daughter’s new milestone.

“To my beautiful, amazing daughter…I can’t believe how old you are now and how much you’ve grown. I am so proud of the girl you’ve become and continue to be each day. I am so lucky to have you as my daughter and so honored to be your dad,” he wrote.

There are no longer children living at Jennifer and Alex’s home. Emme, Max, and Ella are all preteens, meanwhile, Natasha is already a señorita.

Like most dads, it hasn’t been easy for A-Rod to see his daughters all grown up as only a few years ago they were his babies. His older daughter is a young adult, meanwhile, Ella is on her sixth year of elementary school.

In addition to JLo being his leading lady, Alex has found great support in Jennifer with raising his daughters. Tashi and Ella sing the entertainer’s songs and even recreate her dances. Best of all, Jennifer supports them and joins in.

Alex’s girls have such admiration for Jennifer, they’ve already gone to separate some pieces from the singer’s wardrobe. That’s right!

“It’s funny. There are several things she [Emme] likes and wants. Now she always tells me: “Mommy save me this. Mommy save me that,” she said in an interview with People. “Even Alex’s daughters tell me, “I want the dress from the Grammy’s, Emme can keep the other one,” she added.

Until the day in which his daughters are allowed to wear Jennifer’s wardrobe, Alex enjoys every moment with his girls, as, in a few years, the oldest will be going to college. In an interview from his YouTube channel, the girls shared their passions. “Tashi” wants to go to college, get her diploma and do a masters, meanwhile, Ella wishes to enroll in dance. A-Rod will be the first to see his daughter go as she’s the oldest of all four of their kids.

In that same interview, Alex was asked several questions by his fans – among them one of the funnest: “When will he allow his daughters to date boys?” To which he replied in all seriousness: “When they have their master’s degrees.” It’s likely his girls will begin dating ahead of their father’s wishes, and it’s probably only a matter of time before the former Yankee meets one of his daughters’ boyfriends.
