Australian TV anchor Lisa Wilkinson is a seasoned professional with years of experience in front of the camera.
But The Sunday Project host proved she's not immune to a moment of discomfort when she was left speechless by an explicit remark from Tommy Little on last night's episode, News.com.au reports.
WATCH the awkward moment Lisa Wilkinson cracks up here:
Speaking live on air via satellite link from London after attending the Spice Girls reunion tour with Carrie Bickmore the previous evening, Little revealed he had taken part in the city's naked bike ride!
The Aussie comedian admitted it had been a humbling experience, after a passerby remarked on the size of his manhood.
"How's this for shattering? I was still quite cold but I thought, bugger it, I will get nude. Then one woman, she was heckling from the side, yelled - 'He's a grower, not a shower!'" Little said.
An uncomfortable Lisa replied: "I'm not quite sure what that means."
"I think it means I've got a small c**k, Lis," stunning Lisa and the Sydney studio into silence in the final seconds of The Sunday Project.
Red faced, the Network Ten presenter buried her head in her hands and declared: "I'm done."
Australian Spice Girls fans were sent into meltdown when Mel B revealed the group plans to take their reunion tour Down Under next year, but were left disappointed when the now four-piece girl band failed to appear on The Project as expected.
It was thought the group would use the popular programme to formally announce Australian tour dates, News.com.au reports.
