They may no longer be engaged,

on Monday night to cheer on his former fiancée.
Cutler grinned broadly and clapped his hands as Cavallari and pro partner Mark Ballas did an upbeat and sultry samba to "Crazy in Love" by Beyoncé
, earning 24 points from the judges.
Cavallari and Cutler called off their engagement in July after 10 months together, but a source said recently that after a summer apart the pair were "working it out"
