The actress, who plays the haughty Lady Mary in the historical drama, is set to tie the knot to Irish financial PR director John Dineen.

TIE THE KNOT AT HIGHCLERE CASTLE

Although Lady Mary has been far from lucky in love, the drama has played a part in Michelle's happy match. The pair, both 33, were introduced by Michelle's Downton co-star Allen Leech, a.k.a. former chauffeur Tom Branson, and have since been spotted at Venice Film Festival and Wimbledon.
