Chris Brown Dumped on Valentine's Day

It seems nobody wants to spend Valentine's Day with Chris Brown -- 'cause dude just got the boot from a party he was supposed to host that night.

Brown was set to host two separate parties in Scottsdale, Arizona this weekend for the NBA All-Star festivities -- "was" being the key word -- because Brown was just officially replaced with rapper Nelly.
