Rita's loved-up with her DJ boyfriend

Watch out, Cara Delevingne – your wifey’ is falling for someone else.

Cara’s BFF Rita Ora has admitted she’s developing serious feelings for her DJ boyfriend Calvin Harris, 29, who she went public with in May.

‘It’s early. I’m not in love. But I’m definitely falling,’ says Rita, 22.

The Radioactive singer must have had a change of heart after previously declaring quirky model Cara, 20, to be her other half.

‘She’s officially mine. She’s, like, untouchable. I’ve taken her off the market,’ Rita told The Sun earlier this year.

‘We call each other “wifey”. You know what a wifey means? It’s like your other half.

‘Like when you get married, like, that’s your wife!’

Rita’s not always hanging out with her boyfriend or her BFF though.

The singer, who’s signed to Jay-Z‘s record label Roc Nation, admits she still suffers from loneliness when she’s on the road.

‘You always have to sacrifice something when you want to achieve something,’ Rita tells GQ.

‘Of course, I get lonely and I get sad, but I made a decision to do this.

‘I’m in an amazing position to change my life, and change my family’s life.’
