During the stop, Wiz sent a message to his fans, telling the TMZ cameras "Make sure you guys wear your seat belts."Wiz's fiance Amber Rose had a baby shower just hours before Wiz was pulled over. Celebs like Tocarra, Christina Milian, Lola Monroe all attended the event. Amber tweeted, "We had a good ol down home baby shower today. No papz, no booshiness just fun, friends, family, food and good times."Amber and Wiz are expecting a baby boy in February.
