Britney Spears had some very special backup dancers for the final night of her Femme Fatale world tour last night: Her mom, sons, boyfriend, sister and adorable niece!
While the singer usually had been picking some members of the audience to join her on stage to dance when she performed "I Wanna Go" throughout the tour, last night in Puerto Rico her family members popped up on stage instead.
Her mom Lynne, boyfriend Jason Trawick, sons Sean Preston and Jayden James, sister Jamie Lynn and her too-cute-for-words daughter Maddie all danced around with Brit ... and it was pretty adorable.
Also briefly joining Britney on stage during her last show was Pauly D, who had been opening for the pop star on her tour. He was given the night's "Lace & Leather" lapdance -- for the second time!
This time he was reportedly filming it for his upcoming spin-off reality show.
The grand finale of the show was also a bit different this time -- with the dancers surprising Spears with a silly string attack! Check out the photos above.
One of the audience members got video of Spears and her family dancing on stage, check that out below:
