A young woman with Down syndrome has stolen the limelight during a live television cross.

Georgia Knoll, from Mackay in Queensland, has taken the internet by storm after interrupting Channel Seven presenter Scott Linden's Street Talk segment.

'Is someone there?' Mr Linden asks as a giggling Georgia lurks in the background.

Mr Linden gave the excited young woman the opportunity to speak to viewers at home.

'Hey mum, hey dad - love you,' she said.

Mr Linden later posted on Facebook: 'One of the nicest "video bombs" I've had while filming Street Talk. Hi Georgia.'

'I think it was Stacie filming this one on Tuesday, and as I was wrapping up she started giggling and I knew someone was behind me ... just didn't know who until I turned around.

'Thanks to Stacey for keeping the camera rolling (because normally we stop when we get interrupted).'

Mr Linden added it was 'the most memorable Street Talk' in his ten years hosting the segment.

'Thanks for sharing this one around folks, she's a gem,' he said.

Georgia's sister Kathryn gave a 'shout out' to her big sister.

'For anyone wondering, she's exactly the same at home. Always manages to make us laugh. Light of my life and best friend,' she said.

The video has been viewed nearly 3million times.
