What's eating Tara Reid? Or the better question is, what isn't she eating?

The 38-year-old Sharknado 2 star stopped by the Sunset Tower hotel in West Hollywood on Thursday afternoon, looking scary thin in tight jeans and a revealing turquoise top. Tara looked a bit frazzled too, so we're not sure what's going on with her...

Earlier in the day she tweeted, "Just wanted to say thankyou to all my fans from around the world I hope your having a good day or night wherever you are!" Last we checked she was still with longtime beau, Erez Eisen and between Sharknado 3 and the rom-com Tie the Knot, she's still a working actress, so it seems like all is well ... maybe she was recovering from a rough night?
