Britney Spears wished her sons a happy birthday via Instagram this week with a beautiful piece of art and a sweet message.

“My two lil men’s birthdays are this week 🥳🥳🥳 !!!!!!” she wrote in the caption of a picture of a moon surrounded by red clouds with yellow flowers peeking out of them. “You guys are getting older and so big and are waaay cooler 🤪 than me !!!!! I love you both to the moon and back 🌙💞 ….. and I hope all of your bday wishes come true and more !!!!!”

Spears’ sons Jayden James Federline and Sean Preston Federline turned 14 and 15-years-old this week, respectively. Spears shares custody of the children with her ex Kevin Federline. He has custody of them 70% of the time, versus Spears’ 30%.

Spears has been in the news recently as she tries to end her father Jamie Spears‘ sole conservatorship on her finances, health, and career. In August, the singer filed court papers in which she asked that she be allowed to pick her own conservator, and suggested that a wealth management and investment firm be in charge of her conservatorship.

Spears’ sons were given a restraining order against their grandfather last September after Jamie was accused of abusing Sean. In March, Jayden reportedly said his grandfather “was a pretty big d***k” and that “he can go die” in a now deleted Instagram Live video.
