Cara Delevingne and St. Vincent fuel dating rumours in New York

British supermodel Cara Delevingne and singer St. Vincent have fuelled reports of a romance after reportedly kissing and dancing together at a show in New York City.

The runway beauty first sparked rumours she was more than just friends with St. Vincent, real name Annie Clark, at the BRIT Awards in London last week (25Feb15) when she was caught on camera caressing the singer's back as they sat at a table together at the O2 Arena.

They were later photographed attending an awards afterparty, where they allegedly locked lips, and now the reported new couple has continued its rumoured relationship in the Big Apple.

Delevingne and St. Vincent met up with a group of pals, including actress Zoe Kravitz, on Sunday (01Mar15) and headed to the Queen of the Night show at the Paramount Hotel, where an onlooker claims they put on a number of public displays of affection.

The source tells the New York Post, "Cara and Annie snuck off to the bathroom during dinner and slow-danced at the end of the show. At one point they shared a chair and were hugging and kissing."

Representatives for the two stars have yet to comment on the relationship rumours.

Delevingne has previously been linked to One Direction star Harry Styles and Unbroken actor Jack O'Connell, while she split from actress Michelle Rodriguez last May (14) after a brief romance.

Meanwhile, St. Vincent's exes reportedly include Sleater-Kinney member and Portlandia star, Carrie Brownstein.
