The pair, who have been spending a lot of time together recently, were pictured dancing together, kissing and cuddling while out for dinner with Macaulay Culkin and his girlfriend.
Earlier in the week, Jackson posted the below photo of Delevingne, before sharing an Instagram Story showing the two watching a movie in bed.
According to People, "They have a flirty friendship but aren't dating or in a relationship. Paris is 19 years old and living her life. She has no plans to settle down any time soon."
Another source told Page Six that the two bonded over similar interests, but that it's early days. "They’re both really into their music and have been spending nights singing and jamming on the guitar."
"It’s early days, and Cara doesn’t really have time for a proper relationship due to her non-stop filming commitments... but there’s no denying there’s a spark."
