Jennifer Lopez Wrote Alex Rodriguez's Daughter Natasha a Beautiful 15th Birthday Message

It's clear from her Instagram photos that Jennifer Lopez absolutely loves Alex Rodriguez's kids, and she shared some extraspecial love for his oldest daughter, Natasha, on Monday for her 15th birthday. "Wishing my favorite teenager a very happy 15th birthday!!!" Jennifer captioned a photo of her and Natasha hugging in front of a gold-covered birthday cake and a tray of pink doughnuts — what a fun party!

Natasha, or Tashi, as J Lo refers to the 15-year-old in photo captions, wore a beautiful red dress and was all smiles as she celebrated the momentous birthday. "May you forever keep illuminating the people around you with your infectious light," Jennifer added. "I love you and hope you have the best day."
