News about Cara Delevingne's boyfriend may be few but the latest claim that the British supermodel is seeing her "Tulip Fever" co-star, Jack O'Connell. According to a report, the Burberry brand ambassador is "having fun" with the "Skins" actor leading to speculations that they are dating.

The 22-year-old "Paper Towns" actress Cara Delevingne initially prompted rumors that Jack O'Connell is her boyfriend when she posted an Instagram photo showing the back and neck of the actor.

The model-turned-actress captioned her snapshot, "Love bites," with an accompanying heart emoticon.

The Burberry model also added a hashtag #fittybum in the caption.

Though Cara Delevingne did not tag the actor, people identified the person in the photo as Jack O'Connell because of the evident moles in his neck, Heavy.com said.

According to a report from E! News, the rumored couple has been together for a few months.

The insiders claimed that the model and the actor are "having fun" with their relationship.

The report also said that Jack O'Connell is adding Cara Delevingne to his list of relationships, which include "Skins" co-star Kaya Scodelario.

Just recently, Cara Delevingne was rumored to be dating "Come & Get It" singer Selena Gomez.

While the model-turned-actress is plagued with dating rumors, she now focuses on her budding acting career.

This year, the Burberry model is set to hit big screen as she stars in movies "Pan", "Suicide Squad," and "Paper Towns."

Cara Delevingne will also star in the upcoming movie "Tulip Fever" together with Jack O'Connell and Prince Harry's ex-girlfriend Cressida Bonas.
