TORONTO - For two married principal dancers with the National Ballet of Canada, a pas de deux is about to become a pas de trois.

The dance company says Heather Ogden and Guillaume Cote are expecting their first child in December.

Ogden is currently on maternity leave and is slated to return to the stage next June.

The couple met at the National Ballet, with both joining the company in 1998.

Cote, who hails from Lac-Saint-Jean, Que., has been a principal dancer since 2004.

The Toronto-born Ogden has been a principal dancer since 2005.
