Ashton Kutcher and his fiance Mila Kunis took up ballroom dancing classes to stay healthy during her pregnancy.
Sources revealed that the couple has been taking lessons for a long time now as it is the best low-impact exercise for the 'Black Swan' star, who is expecting their first child, Radar Online reported.
Sources added that they were inspired by Bradley Cooper and Jennifer Lawrence's big romantic dance number in 'Silver Linings Playbook', which is their favorite movie.
