The second season premiere of a hit TNT series will feature a prominent new guest star. TV Guide is reporting that actress Debi Mazar will appear as a guest star on the Season 2 premiere of Hawthorne, which will air on Tuesday, June 22 at 10 PM ET on TNT.

The site reports that Mazar will portray Donna Alberghetti, an old friend of Jada Pinkett Smith's character, Christine Hawthorne, who shows up at Hawthorne's hospital with a bizarre illness just days before her wedding, which casts a suspicious light on Alberghetti's husband-to-be.
