Cee Lo Green, the guy who sang the unforgettable "Forget You" while dressed as the world's most colorful peacock at the Grammy Awards, is touring with Rihanna.   (The outfit and the performance, by the way, was a tribute to Elton John.)  It was just announced earlier today, and yes, he's going to be at her Texas dates.  They'll be in Dallas on July 8, and Houston on July 9.  Tickets go on sale this Saturday morning, and something tells me they'll go fast.
