We can't believe how big Sean Preston and Jayden James are getting!

Over the weekend Britney Spears took her boys to Disneyland in Anaheim, and she posted the above photo of the trio and wrote, "Took these two little Mouseketeers to @Disneyland today... like mama like sons ;)." Awww!

Britney is set to start performing in Las Vegas again next month for her Piece of Me residency concert, and though executives are allegedly eager to extend her concert series through 2016, Brit Brit doesn't want the show to go on!

"Britney cannot wait until the Vegas show is done because she wants to start a family with David. She says she will get pregnant as soon as the show is finished! David is always with her in Vegas and they act like an old married couple together. He is really good with her kids and has taken to the father role pretty easily," a source told Radar last week.

And she definitely dropped a hint about wanting to expand her family last year too! In an interview in December 2013 she told InStyle, "I would really like to have another baby, a girl. I think she would be like a mini-me. I think it’s going to be crazy. I’m not going to feel as alone in the world anymore. I’m going to feel like I have a second person, like, that’s me."
