Karina Smirnoff: Is Her Engagement Off?
12/05/2011 AT 06:35 PM EST
Smirnoff, 30, and her pro baseball player fiancé Brad Penny, 33, are calling off their engagement of more than a year, E! Online reports.
"They're just different people," a source tells E! of the pair, who began dating in October 2009 after meeting through former DWTS contestant Chuck Lidell.
Although the ballroom beauty was wearing her engagement ring as recently as Saturday in Las Vegas, there have been signs of potential problems.
During her emotional run to the Dancing championship with partner J.R. Martinez, she never referred to Penny nor was he spotted in the audience.
Smirnoff had said she decided to postpone her upcoming January wedding to focus on Dancing, though she told PEOPLE in February that this time was different from her failed engagement to Maksim Chmerkovskiy because she now had "a man who supports me and loves me unconditionally."
A rep for Smirnoff has not returned a request for comment.
