Trent Richardson parties with Jamie Foxx

Cleveland Browns running back Trent Richardson turned 21 on Tuesday and celebrated by partying with actor and close friend Jamie Foxx in Los Angeles.

They started the night at trendy Mercato di Vetro restaurant in West Hollywood for a dinner of 20 and then headed to Hyde Lounge on Sunset Boulevard as Foxx sang some of his hits -- and even sang "Happy Birthday" to Richardson.
