Two months back, the 37-year-old dancer decided to tie the knot with Adelman after less than a year of dating, reported People magazine.
It was Smirnoff's third engagement.
She was earlier engaged to fellow Dancing with the Stars pro Maksim Chmerkovskiy in 2008 before splitting in September 2009. She later got engaged to Brad Penny for a year in 2011.
A representative for Smirnoff could not be reached for comment.
