"Dancing with the Stars" professional dancer Karina Smirnoff is reportedly engaged to her boyfriend Jason Adelman (some reports have his name as Jason Gale). According to Star magazine, Adelman popped the question on Jan. 10 in front of family and friends. After the 37-year-old accepted, the two reportedly had a small celebration.

"Karina is thrilled and the two couldn't be more in love!" a source told Star. "From the moment they met, Karina has been head over heels."

Smirnoff and Adelman started dating less than a year ago. If the engagement rumor is true, this will be the ballroom dancer's third time sporting a diamond engagement ring. She was previously engaged to fellow "Dancing with the Stars" pro Maksim Chmerkovskiy in 2009 and ended a second engagement to baseball hunk Brad Penny in 2011.

 "Karina is sure that Jason is the one," the source said. "He treats her like a queen and is ecstatic that she said yes."

Neither one has publicly confirmed the engagement but a source told Star that Smirnoff and Adelman will most likely get married before the end of the year.

"Karina wants to get married as soon as possible and definitely wants it to be a big event. She already has visions of exactly what she wants," the source told Star.
