The pop-star posted the cheeky snap on his Instagram page on Friday (26 July), which showed him posing in a funny diving position and sporting some very eye-catching swimwear with the Disney character printed all over.
He wrote beside the picture: "New trunks! Yeah, you know you want some."
And we can't help but notice that Tom, 28, is also flaunting a rather ripped six pack too!
It sounds like the singer has been keeping schtum on his holiday destination though, as he revealed that he'd been trying to surprise his parents by crashing their getaway and didn't want to give his game away.
This morning he tweeted: "My apologies for not tweeting for a few days. I've been trying to surprise my parents on holiday so didn't want them to know where I was!"
Tom - who is happily married to Mario Falcone's sister Giovanna - also broke his brief Twitter silence to congratulate his bandmate Danny Jones on his recent engagement.
Danny popped the question to longtime girlfriend Georgia yesterday (25 July) and since Tom is a newlywed, he was quick to wish his McFly pal the best.
Tom wrote: "Super massive congratulations to @Dannymcfly and @GeorgiaHorsley1 on your engagement!!!!! Bloomin awesome news!!!!!"
He added: "Danny's getting married, Danny's getting married, na na na na hey! Na na na na hey!"
