Lohan undergoes appendix operation

Actress Lindsay Lohan is having surgery to remove her appendix, her publicist said tonight.

In an email, Leslie Sloane Zelnik said the 20-year-old actress was "having her appendix removed. She is resting comfortably".

Celebrity Web site TMZ.com reported Zelnik as saying Lohan was not feeling well yesterday and went to a doctor, who performed several tests and determined she was suffering from appendicitis.

Doctors asked her to return to the hospital today to remove her appendix as a precaution, TMZ said.

Lohan, whose screen credits include Bobby, A Prairie Home Companion and Freaky Friday, was treated for several hours at a Los Angeles-area hospital last July for overheating and dehydration on the set of Georgia Rule.

She was treated at hospitals twice in January 2006 - in London for a cut on her leg and in the Miami area for an asthma attack. In 2005, she was admitted to hospital suffering from exhaustion and lost a noticeable amount of weight.
