Extra footage of Britney Spears performing in Miami.

Britney Spears tells our photographer she loves X17! while shopping in Miami. I hope she feels that way later.

Britney Spears arrives in South Beach ready too enjoy the festivities that Miami has to offer.

The NY Post is confirming rumors that Britney Spears never actually took her plane at LAX on Friday when X17 snapped her there arriving for her flight. But X17 has the real proof here -- the video of Brit's private jet arriving at Orlando International Airport at 2 am on Saturday morning.

Brit was reportedly uncomfortable with her seats on the United Airlines flight she was supposed to take around mid-day on Friday, so she and her girls got off and called for a Gulfstream 3 to pick them up at Van Nuys Airport at 6 pm.

The plane got going an hour late from the Valley airport and arrived in O-Town around 2 am.

Britney Spears went to LAX airport on Friday, preparing to fly to Orlando for her big concert on Saturday, but as it turns out, she got on her United Airlines flight and immediately got off! Rumor has it that she complained the first class seats weren't leather so she and her two girlfriends jumped off, ordered a private jet, and flew aboard a Gulfstream 3 to Orlando! (We have video of their arrival.)

Britney Spear’s home way from home could be the Millennium. Here Spears rehearses at the dance studio then runs off to the recording studio to meet up with producer JR Rotem.

Britney Spears visited the popular outdoor mall The Grove making a stop the Wood Grill for some eats. Spears then milled about the plaza before heading over to the valet. Then the pop star took time to soak up some fake sun at the tanning salon staying inside till after the sunset.
