If you've got nothing better to do around dinnertime tonight, you might as well check out the free Mariah Carey concert and holiday window reveal happening outside of Hudson's Bay/Saks at Queen and Yonge. While it won't cost you a dime to stand outside and watch, Carey's making heaps of money from this show.

According to TMZ, Carey's getting around $1 million to perform two songs, including "All I Want for Christmas Is You" - more like, all I want for Christmas is a million dollar pay day.

This massive window reveal will apparently also feature fireworks. It's even shutting down part of Queen Street and is diverting the 501 between Yonge and Bay.
