Today mark's Jennifer Lopez's 49th birthday and if (for some reason) someone didn't know who the singer was, they would easily guess she wasn't a day over 35. Just the other day J Lo posted a photo of her impressive physique to Instagram and her body is just one example of her determination to keep all aspects of her life and career in shape. 

Today her main man, Alex Rodriguez hit up Instagram to share a special message for his loving lady, posting some never before seen images of Jennifer truly living her best life. In the slide below, we can see a good amount of candid shots of Jennifer on a private jet, riding bikes, dressed to the nines and swimming in the aqua blue water. 

"When we were kids, birthdays were exciting because it was all about the gifts we would be getting. A new bat, dance shoes, maybe a new CD (yes I’m old!). I see firsthand how that’s changed for Jennifer, and how she’s found joy in sharing with others," Alex captioned the photo. "For someone who has been about giving everything she has 365 days a year—to our children, our families, the world—I hope today, we can give you all the happiness you deserve. I love you mucho Macha 13."
