They're at it again, Tom Daley and Dustin Lance Black are proving just how smitten they are with each other.

And it's on an escalator of all places this time.

The pair were spotted in the Westfield Stratford City Mall in London today, just at the precise moment Dustin smoothed a bit of Tom's hair back.

Oh, how perfect.

Olympic diver Tom opted for comfort in an Adidas hoodie, while his partner mirrored the look in his own navy top and trousers.

The pair were spotted sharing a cheeky snog at London nightclub G-A-Y in January - but they've managed to dodge the cameras pretty well since.

In their first public outing together as a couple, an onlooker said they didn't seem to care who saw them snogging.

"As the night went on they became more relaxed, and by 4am they were kissing on the balcony. They weren't trying to be discreet," the onlooker told 3am.

Hunky Olympic diver Tom also had a spin on the decks, playing Sexy and I know It and Rudimental's Waiting All Night to a packed out club.

G-A-Y owner Jeremy Joseph, who got a call saying Tom and Dustin were coming to party, said it's clear the hot new couple are completely besotted with each other.

"You know when two people look at each other like no one else is around? You can see it in the eyes. They're just so natural with each other and clearly in love. They're just being a normal couple now," he told the Mirror exclusively.
