The 'Kiss You' singer is said to have partied well into the night with the 'Radioactive' star.
One Direction star Harry Styles was spotted getting close with both Rita Ora and rumoured former flame Cara Delevingne at the O2 for War Child BRIT Awards 2013 concert last night (18th February) in London.
The 'Live While We're Young' singer stayed close to the 'R.I.P.' singer and supermodel Cara for a night of partying as they watched Muse perform the charity concert at the O2 Shepherd's Bush Empire, before heading on to the Dazed & Confused party in town.
Harry opted for a simple green jacket and grey t-shirt combination while chatting to Rita backstage in the VIP area, who dressed up in a black and white patterned matching jacket and trousers and a bright pink top.
