While fans debate the latest 90210 cast additions, The CW has announced a musical act for the show's fourth season premiere.

Theophilus London will perform on the September 13 episode, performing "I Stand Alone” and “Why Even Try” at a party hosted by Naomi. It will take place in her "new mansion," according to a 90210 spokesperson.

The Trinidad-born rapper/singer will release a new CD, "Timez Are Weird These Days” on July 19.

London isn't the first musician to appear on the show. The Script, Snoop Dogg and Nelly have all stopped by.
