Now, The Shadowhunters star is showing off his relationship with British-South African model, Niamh Adkins.
Niamh’s best friend, Dylan Reynolds, shared a steady pic of the couple while they were celebrating Dom's 28th birthday.
If you follow Dom on social media, then you've probably noticed that the pair have been seeing each other for at least a month now. They took a holiday together earlier in January.
Obviously, fans were wondering if Sarah would do anything on social media, following the confirmation. Since she's not one to usually hold back... we weren't surprised when she uploaded a particularly shady post on Instagram.
"That look you get when you remember on May 6, 2017, 3:17pm, sitting on the couch, he got a text from another girl," she wrote...
Well that's specific.
Fans were clearly shooketh by the confession, needing to know more of what actually went down between her and Dominic.
"Comedy is all about the details," she responded to a fan who asked about the specific time stamp.
WE NEED DETAILS.
