Rihanna is back in a big way. Last week, she caught the stylistas around the world when she wore a yellow sequined jacket out to dinner. Rihanna's Marc Jacobs jacket comes straight off Spring/Summer '09 runway. The singer turned glamutante is just one of the many celebs who've spotted in Marc Jacobs creations in recent weeks. The designer dressed no less than 5 celebs for the Costume Institute Gala. The jacket can also be spotted on Monica in the video for "Trust" featuring Keyshia Cole. No wonder the celebs are going gaga over this piece of bedazzled outerwear. The 80s are back in a big way.
