The former Strictly partners tied the knot at London's St Pancras Renaissance hotel today (December 29).
Cacace shared a photo from the wedding on Twitter, writing: "Had the most amazing day with family & friends @StPancrasRen xxx"
She has also updated her name on Twitter from Flavia Cacace to Flavia Cacace-Mistry.
Mistry - who currently stars in Coronation Street as fitness teacher of Dev Alahan - partnered Cacace in the 2010 edition of Strictly, eventually being eliminated in the seventh week.
He was previously married to Meg Leonard from 2001 to 2010. The former couple have one daughter, Elin Leonard Mistry, born in May 2001.
