The Dancing with the Stars pro and actor Jason Adelman have ended their engagement, TMZ reports.

After dating on and off for a year, the pair announced in January that they were engaged. This is the third engagement Smirnoff, 37, has called off. She was engaged to her fellow Dancing with the Stars pro Maksim Chmerkovskiy in 2008, and then to MLB player Brad Penny in 2010.

A source tells TMZ that Adelman, 37, was uncomfortable with the way Smirnoff acts around other men, particularly other dancers, and believes they have "different family values."

Smirnoff, who won't be on Season 20 of Dancing, is currently in the midst of a promotional tour for her new book, ironically titled We're Just Not That Into You: Dating Disasters from the Trenches.
