Karina Smirnoff and Brad Penny

Dancing with the Stars champ Karina Smirnoff and her fiancé, major league pitcher Brad Penny, have split, Us Weekly reports.

The pair, both 33, had postponed their wedding (set for January 2012) in October and were still together at the time, but had conflicting schedules, a source tells the magazine. Smirnoff was in the middle of the Dancing season and Penny had advanced to the American League Championship Series with the Detroit Tigers.

The two, who got engaged in October 2010, were introduced in 2009 by former Dancing contestant Chuck Liddell, shortly after Smirnoff broke off her engagement to fellow Dancing pro Maksim Chmerkovskiy.

An email to Smirnoff's rep was not immediately returned.
