Lindsay Lohan has taken to Twitter to shoot down gossip she's currently holed up in a psych ward.

Apparently the wayward star's publicist had contacted her to double-check she hadn't come over all Mischa Barton and been whisked away to hospital.

She Tweeted: "Hahahaha my publicist just called me & said she heard I was in a psych ward!!!! Hahaha WHAT IS WRONG with people???? I'm working lol"

She didn't specify exactly what she was working on. A shopping assignment, perhaps?

She added: "BUT that's one I've NEVER heard about myself before! New ones r always interesting huh? There's SO much more going on in the world! Wake up"

See, perfectly sane!
