Cara Delevingne, Jack O'Connell are dating
The 22-year-old model has been previously linked to the likes of Harry Styles and Jake Bugg, reported Daily Mirror.
"Jack and Cara get on really well. So far their relationship is very casual but she's a big fan of him. They've been on a few dates and been seeing each other quite often but it's not yet serious," a source said.
"They met on the Tulip Fever set and hit it off immediately. They are both very busy all the time with work but they could make it work," it added.
