Britney Spears shared a heartwarming Instagram message dedicated to her sons, Sean Preston Federline, 16, and Jayden James Federline, 15.

On Tuesday, September 21, the singer posted a photo that featured the quote, “There is nothing stronger than the love between a mother and a son.”

She captioned the photo, “My boys’ birthdays were last week … and unfortunately they are growing up and want to do their own things ….

It makes me crazy because they are so tall and geez they are still growing 😳😳😳 !!! They went to a dance last week and I cried for two days 😭😭😭 my babies in a suit !!! It’s crazy !!! And girls get ready cause my boys are so handsome 🥰🥰🥰 !!! I truly believe this quote which is why I wanted to share it …”

Spears, 39, added, “There’s a lot I can’t share with you all because my kids are very private which I love but I will tell you they are both extremely talented and I’m so incredibly blessed to have these two little men in my life ❤️🙏🏼 !!! And if they’re reading this … which I’m pretty sure they’re not … I love you two little devils so much 😈❤️😈 !!!”

The pop star, who shares her kids with ex Kevin Federline, celebrated their birthdays this month, with Sean Preston’s being September 14 and Jayden James’ being September 12.

The “Circus” singer explained that she rarely gives an inside look at her children’s lives because they prefer to be out of the spotlight. However, her sons’ recent birthdays was an exception.
