Britney said, "My boys' birthdays were last week ... and unfortunately they are growing up and want to do their own things ... I have to ask their permission to post them because they are extremely independent little men."
She said it's astonishing to her how fast they're growing up ... literally and figuratively. She said it makes her crazy "because they are so tall and geez they are still growing." What's more ... Brit said the boys went to a dance last week ... and it made her emotional.
Britney said, "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!!!"
Britney, who reiterated later in her post there's a lot she can't share with her fans because her kids are very private, ended her post by saying she's incredibly blessed "to have these two little men in my life" and that she loves these "two little devils so much."
