Nicki Minaj Hits Up "Letterman" + Lil' Wayne Tossed In Solitary Confinement!

Nicki Minaj performed on "The Late Show with David Letterman" last night and we have pics of her arrival and video of her performance inside. PLUS, find out why Lil' Wayne was tossed into solitary confinement at Rikers...

Nicki was greeted by dozens of her Barbez--fans--as she arrived at "The Late Show" yesterday:

Can decide how I'm feeling about this look.  Love the print--hate a harem pant.

She hit the stage with Will.i.am to perform their song together.

Meanwhille, news out of Rikers Island-- Lil' Wayne was recently placed in solitary confinement for listening to his music.  WTF?  He wasn't fighting, doing drugs or sneaking phone calls - but "working" on his talent and craft.  But violating the rules is violating the rules.  Earphones and music contraband is illegal at Rikers.  And he was caught with it.
Weezy will be confined to an isolation cell for up to 23 hours a day until his scheduled release on Nov. 5th, a Rikers Island source said.
Mr. Carter was caught with headphones and a charger for an MP3 player back in May and another inmate was found to be hiding the MP3 player itself.  So the infraction itself happened in May, but Weezy is only being punished now because a spot in solitary confinement just opened up on Monday.  I see Rikers Island is more packed than Eddie Long's pews two Sundays ago.
Lil' Wayne was sentenced to a one-year sentence on the Island for getting caught with a loaded gun on his tour bus. And now he won't get any social activities in jail outside of one recreation hour a day and one personal phone call a week.  I am sure he is eagerly anticipating his release.  Seems like a rough living to me.
