Katy Perry and Robert Pattinson have sparked dating rumours as they were spotted on a dinner date together in West Hollywood over the weekend.

According to TMZ, the Roar singer and Twilight star got "super cozy" as they enjoyed each other's company in WeHo restaurant at the Sunset Tower Hotel on Saturday (5 August).

The photos obtained by the news website show the pair dining, with a few other people, under a dimly light table. It is not clear as to whether the people, whose faces are not visible in the snaps, are pals of the British actor and songstress.

The two broke off from the crowd when their photos were taken, according to the news website. For the outing, Perry was dressed in a shiny sheer top, which she paired with large round earrings, while Pattinson sported a black t-shirt and slick black hair.

Perry and Pattinson's outing comes just weeks after the actor, during an interview with Howard Stern, revealed that he was "kind of" engaged to girlfriend FKA Twigs.

When asked if he is set to marry the British singer, Pattinson replied: "Yeah, kind of."

"Kind of!" Stern said. "You're one of those secretive guys with the relationship, right? Protective."

"It's one of the most frustrating things in the world, you want to be able to (be more open), but it's literally like, you get stuck in this position but you have to make this decision whether you want to let the crazy people in," Pattinson said.

"I mean basically, for whatever reason with Twilight – I don't know whether it is a specific thing with the audience – there's like a crack group of crazies that think every single decision you're making is either creating some kind of conspiracy...So you kind of think, like, to protect it, I want to create a big boundary, (but) then it's difficult for your relationship."
