Emmy-winner and Oscar-nominee Shohreh Aghdashloo is making a 'House' call.

According to TVLine, the '24' veteran will appear in the Fox medical drama's season finale. Aghdashloo's role is being kept under wraps, but TVLine's Michael Ausiello theorizes she'll be House's new mother-in-law.

Aghdashloo recently popped up on 'Law & Order: SVU' and before that had guest roles on shows such as 'Flash Forward,' 'Grey's Anatomy' and 'ER.'

I didn't watch the first season of Saving Grace, but over the weekend, I had an opportunity to screen the second season premiere, titled 'Have a Seat, Earl.' The show is gritty and heartbreaking, and it's shooting to the top of my Must-Watch List.

First of all, let's get this out of the way: I want Holly Hunter's body. The girl just turned 50 in March, and her body is as fit and toned as a 20-year-old triathlete. Only better, because she's got all the wisdom of a 50-year-old soul.

OK, on to the story. I won't give a blow-by-blow of the episode, which premieres July 14, 10/9c on TNT, but I will talk about key plot-points, so if you're averse to spoilers, you'd best quit reading here. Don't say I didn't warn you.
