Bye, bye blonde!

Channeling her former days on Cheers, a newly slimmed-down Kirstie Alley decided to revisit her 1980's roots by dying her blonde hair a rich chocolate brown. We like!

The former Dancing with the Stars champ shared a pic of her new 'do, after going dark at the Sally Hershberger salon.

Alley Tweeted:

    "OK..I have dark brown hair..taking it out for a spin tonight...my verdict isn't in on it yet...I'll send some pics..;)"

But this isn't the only change Alley has gone through this year! "I've lost 100 pounds," she told Entertainment Tonight in September. "I feel like I'm back in my element -- I honestly didn't even realize what I looked like."
