Prince is in the midst of a 21-date residency at the Forum and has had many special guests come up to perform with him during his sets, including Chaka Khan, Alicia Keys, and Gwen Stefani. At his latest show on Saturday, Nikka Costa came on to sing Led Zepplin's "Whole Lotta Love".

Prince is such a bad-ass! SoCal people, you need to see this man perform while you can. Tickets are only $25 (with no fees!) in some of the middle sections and all of the upper. The seats are good everywhere. I saw him on Thursday, and he sang till 12:45 am with four encores. It was incredible.
