Fresh off another season of competing on Dancing with the Stars, Karina Smirnoff took some time out in an environment that provided a different kind of pressure than she's used to in the ballroom.

In between taking in a performance by Natasha Bedingfield at the recent Lupus LA Orange Ball in Beverly Hills, the Russian beauty headed over to the event's Dyson vacuum table, where she talked about how her temptations were being tested that night.

"She said that with the show on its off-season, she has been making an extra effort to stay in shape," a source tells PEOPLE. "She said she was tempted inside the event by the edible centerpieces which were made out of cookies and other sweets."

According to the source, Smirnoff, who autographed one of the vacuums for charity, "came alone and looked cute in a red dress."
