Scottish singing sensation Susan Boyle has appeared on the big screen in a suprise cameo in Zoolander 2.

The Britain's Got Talent star features in a scene set in Rome as models Derek Zoolander, played by Ben Stiller, and Owen Wilson's character Hansel arrive at the airport.

The dim-witted fashionistas assume a crowd of paparazzi at the end of a moving walkway are there for them.

But then Subo bursts through them and makes a rude gesture before inviting the photographers to take her picture. 

Movie fans have been taking to Twitter to express their delight at the cameo.

Zoolander No. 2 will be released in UK cinemas on February 12.
