Is this his number one fan? Hugh Jackman playfully admires small propeller attached to his phone while watching the US Open semi-finals

He has a large following of fans across the globe with over 7.7 million followers on Instagram alone.

But it would seem that Hugh Jackman has picked his favourite fan, which just so happens to have the ability to attach directly to the back of his Iphone.

The blue propellered device appeared to amuse the Australian star who shifted its direction towards his partner Deborra-Lee Furness while in the audience of the US Open men's semi-finals on Friday.

Hugh and Deborra-Lee looked perfectly in sync while attending the event with coordinated outfits for the match between Novak Djokovich and Gael Monfils.

Taking to the photo wall, Hugh cut a suave figure in a crisp white button-up shirt while draping a navy suit jacket over one shoulder.

Looking like the bonafide movie star he is, the Sydney-born actor accessorised with a leather banded watch and pair of tinted sunglasses.

Deborra-Lee opted for a sheer white blouse teamed with a simple tank top underneath to conceal her modesty.

Sporting eclectic round-rimmed sunglasses, she swept her fair tresses into a casual up-do and appeared to sport a minimal amount of makeup.

But for the Wolverine star, the Iphone attachement was the star of the show, drawing attention away from the game.

Hugh looked pleased with his tiny fan and appeared to demonstrate how the device worked to a friend who was sitting behind him and Deborra-Lee.

Shifting his gaze back to the gruelling match, Hugh appeared to be uninterested in his partner's phone which she brought out after seeing the tiny application.

The X-Men star looked to be in deep concentration during a nail-biting moment while Deborra-Lee was equally enthused, drawing Hugh's attention to something in a nearby stand later in the game.

Deborra-Lee has also had a long and successful career on Australian television, finding fame in 1988.

She then met Hugh on the set of Correlli back in 1995.

The loved-up couple were married the following year in Melbourne.

After 20 years together, Deborah and Hugh jetted to the Caribbean island of St. Barts in April to celebrate their milestone.
