Socialite Paris Hilton is enjoying 2008 - because she's "never been happier". The star, who is currently promoting new movie The Hottie And The Nottie, had a troubled 2007 which saw her serve a 23-day prison sentence in June (07) after being found guilty of violating her probation stemming from a 2006 drink-driving arrest. But Hilton insists she has put her dark past behind her and is firmly concentrating on her acting career. She writes on her MySpace Internet page, ""Hey everyone! Hope you all had an amazing new year so far. I have, and I've never been happier. Last night we had the first screening of my movie The Hottie and the Nottie in Dallas, Texas, at the Regent Park Theater. "It was so exciting to be watching it for the first time with a live audience and the response was incredible. It made me so very happy and proud to be a part of such an amazing project."
