Rugby league legend Lote Tuqiri jokingly put his hand up upon hearing the question, with Bachelor star and new dad Matty J agreeing that the former Wallabies player is packing some major heat.
"He's a big boy," said Matty, who recently welcomed his first child with Bachelor star Laura Bryne.
Robert 'Dipper' Dipierdomenico also confirmed: "Lote, yeah big Lote. Big, big man."

However, it seems we might have a definitive answer from host Shane Jacobson, who claims it's not Lote!
"I know the answer to this question. It's George Burgess," said the Australia's Got Talent host.
Entertainer Sam Moran also backs Shane's claims, telling the camera: "It would have to be George. Because George is a mountain of a man."
"He said that it might hit the ground," AFL great Brendan Fevola then said.
After hearing their claims, the NRL star grinned at the camera before cheekily claiming, "We'll see, well let the crowd decide, hey?"
Well played, boys!
