The singer and actress, who turned 45 years old today, got a shout-out from Smart on Twitter earlier today.
"Happppppppy Birthday to the most Beautiful lil bear in the world!!!! May all your wishes come true!! @JLo," Smart wrote along with a photo of a cake shaped like a big pink bear. Now isn't that sweet?
While Lopez has yet to publically respond, we bet she appreciates the message.
As for how Lopez is celebrating her big day, she's been hanging out with friends, including her BFF Leah Remini. Lopez took to Instagram to share two pics of herself and her gal-pals enjoying a low-key day together.
Lopez and Remini have been having quite the week of fun together. The other day, they took their kids horseback riding. And before that, they soaked up the sun while tanning in sexy barely there bikinis!
Nothing like a week of rest and relaxation for your B-day, right?!
