Olympic diver Tom uploaded a photo of himself and screenwriter Dustin together in Washington DC just before the holidays, posing for a selfie outside the Capitol Building.
He added the caption: "Biggest Christmas tree ever!! #tbt @dlanceblack and I in DC just before Christmas :)."
Tom, 19, was in the US in December as he'd been training at a diving centre in Houston, Texas. It was here that he and Dustin were photographed together for the first time, sparking rumours of a romance (which they confirmed last weekend by posing for a picture together after a taping of Tom's show Splash!)
The diver jetted back to the UK on Christmas Eve but clearly not before taking in some tourist sites in the capital with his Oscar-winning boyfriend.
While the couple spent Christmas on opposite sides of the Atlantic, they rang in the New Year together after Dustin jetted over to the UK to join Tom and his friends for the celebrations.
They started the New Year with a visit to Stonehenge, where Tom posed alongside his friends but Dustin, 39, stayed away from the cameras. Dustin later shared some more pictures of himself visiting London tourist spots with his boyfriend's pals.
Dustin was also in the audience for the premiere episode of the second series of Tom's diving show Splash!, which aired live on ITV last Saturday.
Afterwards, they were seen enjoying a post-show dinner together in central London before partying at G-A-Y club where former X Factor contestant Luke Friend was performing.
Dustin jetted back to the US on Wednesday (8 January), but not before tweeting Tom and his friends to thank them for a "beautiful start to 2014."
Tom, meanwhile, will be back on our screens this Saturday night when the second episode of Splash! airs. The reality show challenges celebrities to learn the intricacies of diving and then show off their skills in front of a live TV audience of millions. Eek.
Boyzone heartthrob Keith Duffy will be among the stars competing this weekend (yes, we know, Tom and Keith in Speedos) so mark it in your diaries! Saturday, 11 January at 7pm!
