Image Credit: Michael Desmond/The CWDrumroll, please: Adrian Grenier will appear in the Sept. 27 episode of 90210, has learned. The Entourage star pops up on the CW drama in a musical context, though. His real-life “new wave folk” band, The Honey Brothers (in which he plays drums), performs at an over-the-top 18th birthday party for Naomi (AnnaLynne McCord), who tosses a flirtatious quip in Grenier’s direction. 90210’s third season begins Sept. 13.
