Welsh actor Tom Cullen will be the newest heart-throb on Season 4 of Downton Abbey as he plays Lord Gillingham.  It is rumored that Lord Gillingham will be Lady Mary’s new love interest as she finishes her grieving for poor Matthew Crawley (Dan Stevens).  But is Tom available off-screen as well?  Sorry Downtonians, he is taken.

Unfortunately for us, he has a girlfriend.

Tom and Tatiana Maslany have been dating since last September. The 27-year-old Canadian actress is best-known for her role on the sci-fi thriller Orphan Black.  She also appeared in the film The Vow.

The happy couple hasn’t confirmed how they met but most bets are that they met each other on the set of the epic World Without End.
