Fact Check: Is Tom Cullen Secretly Married? the Truth Behind the Downton Abbey Star's Status
To understand Cullen’s current romantic footprint, one has to examine his most public relationship. Cullen and Tatiana Maslany met in 2011 on the Budapest set of the television miniseries World Without End. Their creative and personal chemistry was immediate. They began dating shortly thereafter, creating a supportive partnership that spanned both actors' breakthrough career phases.
Between 2011 and 2019, the pair were fixtures on international red carpets. They collaborated closely, appearing together in the film The Other Half (2016) and Cullen’s directorial feature debut, Pink Wall (2019). Cullen frequently praised Maslany's fierce talent, while Maslany credited Cullen with keeping her grounded during the grueling multi-character demands of Orphan Black.
The relationship ended quietly around the beginning of 2020. Neither Cullen nor Maslany released sensational statements or courted media spectacle; they simply ceased appearing on each other’s social media feeds and attended events independently. Any lingering speculation that the two might reconcile ended in 2022, when Maslany publicly revealed on The Late Show with Stephen Colbert that she had married musician and actor Brendan Hines. Maslany's marriage inadvertently sparked confusion for Cullen, as casual readers scanning headlines often conflated Maslany’s new husband with her long-time former partner.
