interesting domain. i think you might do well finding an end user that is looking for it. gossip blog type folks or Hollywood rumor sites. Just an idea. I personally have no idea what it would be worth. Good luck with it though!
Oh yeah. i totally forgot about the spelling difference. We spell it the same in Canada. Mjewel is right though - that will definitely lower your value.
The American spelling would definitely add some value in resale but if you find a Canadian or UK buyer, you could do well. Obviously the .com would be much better but still a solid domain for the right purpose.
