Bachelor Castoff to Rebound on DWTS

Melissa Rycroft has dried her tears and put on her dancing shoes, People reports. Only days after being jilted by Jason Mesnick on The Bachelor—and renouncing reality TV altogether—Rycroft has agreed to compete on Dancing With the Stars' Monday premiere. She will fill in for Access Hollywood host Nancy O'Dell, who bowed out with a knee injury. In other gossip news:
