According to reports, Tom only popped the question two weeks ago yet they have already walked down the aisle in London and are now man and wife.
The actor confirmed the happy news by sharing two pictures of himself and his beautiful bride Jessica on their wedding day with his Twitter fans.
Alongside one snap, he commented: "Couldn't be happier. (Thanks to @antoniakinlay & @LaurenRCrace for these lovely pics) X."
He also shared a gorgeous black and white wedding photo.
Jessica, who plays midwife Jenny Lee in the BBC One drama, looked stunning in a lace mid-length gown. She wore her hair in a pretty plaited up 'do and carried a posy of purple and white flowers.
Tom, meanwhile, who played Dr Mawsley in ITV's Mr Selfridge, looked seriously dapper in a grey three-piece suit and red tie.
