Now that the holidays are over, it's back to the ol' grind for Britney Spears!
The blonde beauty is in Las Vegas, getting ready to take the stage at Planet Hollywood once again.
And to prove it, she shared the sweetest snap on Instagram Sunday with her not-so-little boys Sean Preston and Jayden James (above)!
This flawless photo of her famous family wasn't the only one though! In fact, the 34-year-old also posted this precious pic, too (below)!
