In Touch Weekly has a short report stating that Kirstie Alley will be appearing in season 11; and that her partner will be Maksim Chmerkovskiy.
The Kirstie Rumor has been around for a few seasons - mainly because Kirstie seems to be constantly lobbying the producers. Perhaps, there is some truth in it this time particularly as it has specific detail i.e. who her partner is - Maks.
I'm pretty sure Maks won't be happy - Kirstie hasn't got much chance of winning and I'm not sure she would take it as seriously as Maks would want her to.
I think she's going to be great - funny, happy and larger than life. I also think she won't be around that long, but who knows - she may not even be appearing!
