PHILTONPART2BIKE051007_01.jpgParis Hilton PHILTONPART2BIKE051007_10.jpgOnce again, we caught Paris Hilton meeting with her trainer - but this time, they weren't meeting at the gym! Instead, Paris chose to get some fresh air and sunshine while she still had the chance, hitting a bike trail up in the hills as her trainer kept her motivated. Most importantly, though, Paris finally started working her cheek muscles again as she posed with fans outside of her house and flashed what feels like her first smile in a week. Let's hope this clip of Paris and her trainer leaving our cameraman in the dust brings her another one!
