Fresh from the Splash! finale at the weekend, the Olympic medallist was among the stars arriving for Wednesday night's (19 February) Brit Awards 2014 at the O2 Arena in London.
Tom walked the red carpet solo but did bring a friend along for the night: his cousin Samuel.
Posting a pic of them together on Instagram, he joked: "At The Brits with my COUSIN Samuel Daley… haha… #HeIsNOTmyboyfriend."
The 19-year-old's actual boyfriend, Oscar-winning screenwriter Dustin Lance Black, jetted back to the US a couple of days ago for work following a lengthy stay in the UK, where he was supporting Tom every weekend at the Splash! tapings.
ITV's Splash! ended its second series with an all-male finale that pitted Diversity's Perri Kiely against Boyzone singer Keith Duffy, TOWIE heartthrob Dan Osborne and Paralympian Richard Whitehead.
The show was eventually won by Perri, 18, who managed a perfect score in his solo dive, but we reckon many viewers' highlight of the night will have been Tom performing his synchronised dive with Dan O.
