D'you like the photo? Thought you might. It's the closest we'll get to catching his eye across a crowded room too.

Anyway, we have 'pals' in quotes there as really it's their PR people who'd be squealing with glee if this pair actually got together. And, if rumours are to be believed they've already enjoyed a bit of sumhin', sumhin' a year ago.

The Dark Horse singer and the Twilight star were seen spending the majority of their weekend together at Coachella, having both split with their former partners, and friends of the pair are said to be rooting for them to get together.

A source said: "The pair had a fling a year ago but they went their separate ways after John [Mayer] wooed Katy back and Kristen [Stewart] made it clear that she still wanted her Twilight co-star. But things have gone cold with R-Patz and K-Stew since, with them both deciding it's time to move on."

Rob split from Kristen last year when it was revealed she'd been having something of an affair with her Snow White and the Huntsman director Rupert Sanders.

Meanwhile, Katy broke it off with her other half earlier this year and mutual friends are hoping that she and Rob will finally get together now their exes are out of the way.

The source told The Sun: "Katy and Rob are the best of friends with a very strong sexual chemistry. They care a lot about each other but have always been careful not to upset Kristen. But Kristen's off doing her own thing and accepting it's time for both of them to move on. Friends genuinely want to see them get it together properly. They think they bring out the best in each other."

In the meantime, Katy still wants people to think she's dating this... and this...
