Eagle-eyed viewers have taken to Twitter after spotting just how much Tommy looks like the US reality star, who is married to former Hills co-star Heidi Montag.
There is the blonde hair, check! The blue eyes, check! And the blonde facial fuzz, check!
Basically, Tommy and Spencer are twins!
Remarking on just how similar they look, once fan tweeted: "Never clocked how much Tommy Mallet from #TOWIE resembles Spencer Pratt from #TheHills!"
Another added: "When did Spencer Pratt move to Essex and get a cockney accent!? lol #TOWIE #TommyMallet."
And one follower said: "Does anyone else think @tommy_mallet looks like Spencer Pratt from The Hills?!"
We have to admit, the similarities are striking. BUT, it is fair to say they do not have a similar personality.
He may be part of the competitive Team Real, but Tommy isn't quite as scheming as Spencer Pratt!
