Kanye West is on the fast track with more than just Kim Kardashian.
The rapper, who earlier this week announced he's expecting a baby with the reality-TV star, was pulled over by West Hollywood police late Wednesday night outside Chateau Marmont for allegedly speeding and having tinted windows, reports E! News.
West was apparently driving Kardashian's Mercedes Benz G63 SUV.
Lucky for him, police let the rapper off with a warning.
