During the Purple One's concerts, he brings people on the floor to come up on stage for a little dance party during one of his numbers. Loads of celebrities from the VIP section have been on stage; last Saturday, it was Gwen Stefani, Gavin Rossdale, Kirstie Alley & Maksim Chmerkovskiy. This week, Adam Lambert and Nicole Scherzinger joined the party.
Here's a little dance-cam video of Adam, Nicole and others dancing on stage:
And I will say this again (for the umpteenth time) ... if you are in Southern California, GO SEE this dude in concert. He's about halfway done with his 21-night stand in LA, and you are missing out if you haven't gone already. Tickets are as low as $25, and a good amount of those $25 seats are in really good locations. Shows are on Thursday-Friday-Saturday. Opening acts are stellar (tonight's was Esperanza Spalding), and surprise guest performances are abundant (Nicole Scherzinger and Sheila E. tonight, Whitney Houston on Thursday).
