REFORMED party girl Tara Reid is starting a new career: restaurateur. The actress, 31, is opening a new fast-food joint called Ketchup in Los Angeles on March 31. "You probably won't see me behind the cash register," Reid told In Touch. "But I'll definitely be in the kitchen making sure everything is done right." Reid has invested in three other L.A. eateries (Bella, Geisha House and The Shore) and grew up in the business - her family owned a tavern in New Jersey.
