Read Jennifer Lopez Lovely Birthday Message to Twins

The Shades of Blue star, 46, took to Instagram on Monday to share a sweet photo of her "coconuts," Max and Emme, blowing out their birthday candles.

"HAPPY BIRTHDAY TO THE LIGHTS OF MY LIFE. You have brought me nothing but joy and happiness since the very second you were born. I am so proud of who you are and the beautiful loving caring people you are growing into," J.Lo wrote, adding, "#coconuts8thBirthday. #Iloveyoubeyondforever #maxandemme #February22nd.'

The American Idol judge spoke to ET in November and explained that no matter how busy her schedule is -- spending quality time with her children is always her top priority.

"I have to see them because if I don't see them and they don't see me, then it's not happiness," Lopez explained. "Like, this morning I had to work out, then I sit down and I have lunch with them before I come over here and then I go, 'You know what? Since we're shooting all the way through, I'll have the kids come over at 6:30. They can bring me dinner because we had some leftovers.' Every day is like that!"
