Tara Reid is looking way too skinny!

The skeletal star turned up last night wearing a small ensemble to the Dis-Ease event, which is an art showcase by Billy Idol drummer Billy Morrison. The Sharknado actress attended the bash, which was held at Los Angeles' Mouche Gallery, in a pretty revealing outfit. The pics have people talking about the party girl's appearance -- but for all the wrong reasons.

The 39-year-old actress' highlighted her scary skinny frame with a tiny black playsuit that had some major cut outs. It's like the American Pie actress has no idea that she doesn't look hot -- she looks like she needs help!

The blonde's face may look cheerful but those old-lady thighs don't lie ...

Someone get this girl a sandwich -- or some therapy!
