‘Grow your hair and we’ll get married!’

He’s not really a fan of her bleached blonde crop

We were never really convinced that cutting off all her hair and bleaching it blonde was Katy Perry’s greatest style move. And it seems Orlando Bloom agrees – in fact, it could be the one thing stopping Katy from getting her dream wedding.

The pair were spotted looking cosy at an Ed Sheeran concert last week, and heat can reveal things are firmly back on for the former couple. And friends are convinced they will eventually make things official – but it seems that Ms Perry’s a ponytail short of walking down the aisle.

“Orlando hates her new hair – he wants her to grow it for the wedding, should there be one,” says heat’s source. And their inner circle are sure they will get wed. “Orlando gets on with Katy’s family, plus he’s a great dad and wants more kids, which Katy’s wanted since the start. She’ll do anything to make it happen.”

The couple split earlier this year, but after Katy’s recent intimate dinner date with Robert Pattison , Orlando, 40, realised what he was missing and asked her out again. “Katy has a hard time making a break-up stick – she went back to John Mayer at least twice before they finally ended it,” says our source, who adds that the May wedding of Orlando’s ex-wife Miranda Kerr, mother of their six-year-old son Flynn, to Snapchat founder Evan Spiegel was a major factor in his change of heart. “Orlando sees how happy Miranda is being married, and how nice it is for Flynn, and started to question whether he wants to be single.”

Our source adds that the idea of Miranda trying for another baby has left Orly “very broody.”

Take note, Katy – they can do wonders with hair extensions these days.
