The Artist Still Known As Prince recently invited reality star Kim Kardashian to join him on stage during a recent concert in New York.  But when Kim wouldn't get into the groove on stage, his royal purpleness kicked her off!  See the video and pics from the show inside, plus get the deets on Trey Songz and his manager being sued  for $18 million for stealing the song "Bottoms Up."

Cee-Lo was the opening act as Prince and his "Welcome 2 America" Tour swept through Madison Square Garden in NYC last night.

And we are loving the gold sparkles.

Later on during the show, Prince had a surprise for the audience.

As he stopped through and got the room rocking, he invited a few of his fans on stage. And who wouldn't be excited to dance with Prince?!

Kim K to answer that question.  He brought Kim on stage and the girl wouldn't move! We all know she's a bit stuff when it comes to moving the hips.  Can you imagine being invited to dance with Prince....and not taking that opportunity? All she had to do was sway from side to side. At least fake it Kim damn!  Shouldn't be that hard for you...

But Prince was not bothered.....he kicked her off the stage. Womp Womp.

Sh went back to sit with her Nets baller boo Kris Humphries.

In other music news...

Derrick Price, Doc Mob Records and IHip Hop Music have filed an $18 million lawsuit over the rights to the music on the hit song "Bottoms Up."  The lawsuit names Trey Songz, Atlantic Records, Kodak, manager Gee Robertson, producer Kane Beatz and others.

Filed on February 2nd in New York city, the suit claims that Doc Mob hired producer Milton James aka "Tony Scales" to produce the original, copyrighted track for "Bottoms Up" for his company, Doc Mob Records. The suit further claims that track was produced in Derrick's home studio.

After Milton allowed Kane Beatz to add production to the song, it eventually ended up on Trey Songz'  album Passion, Pain and Pleasure.  Having a hit song on a hit album should have been exciting for Doc Mob; however, the album only lists Kane Beatz as producer of the song.  Womp Womp.

Doc Mob's Derrick Price says he sent multiple cease-and-desist letters to Atlantic Records and Trey Songz, but they were ignored.  And now Kodak has been added to the $18 million dollar lawsuit, because they used the song in an advertising campaign featuring Trey Songz.

SMH.  Since Derrick has a copyrighted version for "Bottoms Up," it looks like he has a good case.  And whoever ignored those cease-and-desist letters may be looking for a job soon....
