Seems like the sizzling quotient in her new movie, Dirty Picture is already giving Vidya Balan the fever.

The acclaimed actress was to do a series of reading workshops with Tusshar Kapoor over the next couple of days, but unfortunately for her, Viddy woke up on Thursday morning with high temperature and unbearable body ache, informed a unit member.

Since director Milan Luthria couldn't hold the workshop without his onscreen Silk Smitha, he has cancelled the sessions until she recovers.
