Britney Spears Shares Rare Photo Of Her Teenage Sons

It's hard to believe time can pass so quickly! One day we're listening to our walkmans, watching Beverly Hills, 90210 without a care in the world, and the next, you wake up with aches and pains and the realization that Britney Spears can TEENAGE SONS?!

It's hard to believe, but yes, that much time has passed.

Britney Spears has been on everyone's minds lately.

And while that's nothing new for me, for others, it's less common. This fascination has been sparked by the new documentary Framing Britney Spears which outlined the horrible treatment Britney underwent during the first decade of her career.

As fans will recall, Britney always knew she wanted to be a mom, talking about it in interviews often.

After marrying Kevin Federline in September 2004, Britney became pregnant with her first baby.

Sean Preston Federline was born on September 14, 2005. Britney would give birth to a second son, Jayden James, just one year later on September 12, 2006.

Fans would see glimpses of the boys every now and then, but for the most part, their lives have been kept away from the cameras.

Now, Britney is sharing sweet new pictures with fans of her TEENAGE sons, and it's almost crazy to believe how grown up they are!

The picture shows Britney smiling alongside with sons Jayden, 14, and Sean Preston, 15.

"It’s so crazy how time flies .... My boys are so big now !!!" she captioned the post. "I know … I know … it’s very hard for any mama especially a mama with boys seeing them grow up so fast !!!! Talk about enough to make you go to your knees ... GEEZ !!!! I’m extremely lucky because my two babies are such gentleman and so kind that I must have done something right!"

"I haven’t posted pictures of them for some time cause they’re at the age where they want to express their own identities and I totally get it .... But I went out of my way to make this cool edit and guess what .... They’re finally letting me post it !!! Now I don’t feel left out anymore."

"and I’m gonna go celebrate .... Oh [expletive] I guess cool moms don’t do that ... Ok I’ll just read a book instead," she concluded.

To lovely to see Britney spending time with her boys! I can't believe how grown-up they are!
