It is not a good time for endorsements involving famous young men. While Michael Phelps is being dropped from his endorsements over suspicions of marijuana use, Wrigley is suspending its advertisements with R&B artist Chris Brown pending an investigation of domestic violence.

Brown, 19, is known for hits like Kiss Kiss and Forever, which was an extended version of a jingle for Wrigley's Doublemint gum. He was charged with making criminal threats after an altercation early Sunday morning. The victim is reportedly Brown's girlfriend and well-known signer Rihanna. Brown turned himself into the LAPD on Sunday evening and neither he nor Rihanna attended last night's Grammy Awards.
