Katy Perry's back with her ex... no, not Russell but rocker Rob Ackroyd

Katy Perry's back with her ex... no, not Russell but rocker Rob Ackroyd

Russell Brand’s gone for good but it looks like Katy Perry’s having a change of heart over her other ex-beau, rocker Rob Ackroyd.

The singer and the Florence And The Machine guitarist shared an intimate dinner this week after he whisked her off for, er, a pint and fish and chips at his East London local.

Lovely jubbly.

Katy, 27, flew in from LA on Wednesday ahead of a gig this weekend and immediately met up with her former flame.

The pair then headed off for a night “dahn” The Dove in Hackney.

What more could a girl want?

The couple, who hooked up at Coachella festival in April, were believed to have cooled their relationship.

But onlookers at the Broadway Market boozer said they looked as cuddly and loved-up as in the dream fields of LA.

Except this time with Pixie Geldof in tow...

One fellow diner said: “Katy didn’t seem to care that they weren’t in a fancy, expensive restaurant.

“She was giggly and happy with Rob and some friends, and she even sneakily held his hand under the table.”

My source added: “She was saying she was excited to be back in London. She was saying how much she loves it here.”

Despite her previous tour guide surely...

In the UK: Katy Perry during filming of the Graham Norton show last night

The California Gurls singer’s divorce from Russ, 37, is set to be finalised in July after the pair ended their 14-month marriage.

Touchingly, her ex joked he is on the hunt for a “new wife” at the MTV awards over the weekend.

And it seemed a case of Russell Who? after Katy sunk a few with Rob who then steered her into a Mercedes to drive a mere two streets away to a warehouse party.

There they (no doubt) drank warm beer and danced to dubstep â€" until 3am when they went back to Katy’s hotel.

Asked whether she was dating at the moment, Katy said last night: “My dance card is so full. I don’t know who I’m dancing with.”

Rob Ackroyd at a warehouse party, maybe?
