Bella and Duke were introduced to one another while the actor was on a trip in New York City – and sparks immediately began to fly

Bella Hadid has reportedly been secretly dating Jack Nicholson’s lookalike grandson.

The supermodel, 24, hasn’t been linked to anyone since ending her on-off relationship to singer The Weeknd last year.

However, it’s believed that the brunette bombshell has been enjoying a quiet romance with 21-year-old Duke, who has followed in his famous grandfather’s acting footsteps.

The lovebirds are reported to have ‘went away’ together to celebrate the model’s 24th birthday last week ahead of her girls’ trip, which she’s been documenting on social media in recent days.

An insider close to Gigi Hadid’s youngster sister told Page Six the pair are only in the early stages of their relationship, but are already head over heels for one another.
