Nicole and her filming crew were left terrified when armed gunman stormed their convoy.
The 33-year-old singer was travelling with her crew through a remote mountain area in Mexico when they were surrounded by at least a dozen masked men wielding machine guns.
Nicole, travelling with X-Factor choreographer Brian Friedman, was hoping to film the music video for her latest single 'Try With Me' before the ambush.
A source told The Sun: "Nicole and everyone in the car were terrified. There was lots of screaming and shouting. They thought their time might be up."
"There were around a dozen men with their faces covered, pointing guns at the three cars in her fleet."
"A load more men were in the bushes at the side of the road pointing guns, too. The group knew the dangers, which is why they had a bullet-proof car and security. But no one expected that."
The men reportedly tore apart her armoured 4x4 vehicle and she was only saved when local police arrived on the scene.
