A grandmother had to be dramatically rescued in Iceland after the 'ice throne' she was posing on for a photo drifted out to sea.

Judith Streng was visiting Iceland's Jökulsárlón Lagoon with her son recently when they came across the chunk of frozen water shaped like a throne on the beach.

The 77-year-old, who lives in Flower Mound, Texas, decided to sit on the ice chunk and pose for a photo.

But just moments after smiling for the camera, the makeshift seat was carried away from the shore by a large wave.

Just moments after sitting on the ice chunk to pose for a photo, Streng was swept out to sea when a large wave came along and carried her off

'It was shaped like an easy place to sit... I thought that looks like fun,' Streng said in an interview on Good Morning America of the moment she decided to pose.

'When I got on it started to totter and a wave was coming in, a very large wave came in and made the throne kind of rock and I could tell I was slipping off.

'I thought it was safe. I don't weigh very much so it was a little easier to float off I guess.

'I've always wanted to be queen... that was my chance.'

A bystander, who happened to be a boat captain and was trained in water rescue, had to help bring the grandmother back to shore.

The photos have since gone viral.

After labeling his mother an 'iceberg queen', Streng's son said she had 'lost her kingdom when she drifted out to sea'.

Another text read: 'No joke. A coast guard rescuer had to save her and bring her back to shore.'

Streng's granddaughter shared the story on Twitter, saying: 'My grandmother almost got lost at sea in Iceland today lmaoooo.'
