Rita Ora and superstar DJ Calvin Harris confirmed their new relationship as they attended their first public party together.

After weeks of speculation, Rita Ora and Calvin Harris have finally confirmed their new relationship.

The Shine Your Light singer and the superstar Scottish DJ went public with their budding romance at the listening party for Daft Punk's new album Random Access Memories.

Arriving hand-in-hand for the event in the Shard in London, theor public debut as a couple caused a stir and they were flanked by police as they headed into the venue.

Ora, 22, opted for a dressed-down outfit in a baggy pink polo neck jumper, white rolled-up jeans and matching heels. She completed her look with a bright yellow quilted Chanel handbag.

Harris, 29, also chose a causal outfit of a long sleeved black jumper and charcoal grey trousers.

Onlookers at the party said the pair could be seen indulging in some PDA throughout the night as they openly kissed in front of the other guests.

Ora, who split from reality star Rob Kardashian at the end of 2012, is said to be head over heels with Harris after they spent a weekend in Las Vegas together, where he was performing at the Grand Hotel's new club, Hakkasan.

"She was in the DJ booth during his entire performance and the two were seen getting really cosy and kissing," an insider told the New York Post's Page Six.

Harris hinted to fans on Twitter that things were heating up between them by posting a photo on Instagram showing Ora boarding his jet along with the caption: "You again!"

Friends of the pair have described them as a "perfect couple".

"They are having a great time and are really into each other," said one.
