According to Travis singer Fran Healy, the Coldplay frontman never rests and is the most active person he has ever met.
Scottish rocker Fran said: "Chris Martin doesn't sleep. I don't necessarily think he could sleep any better before he got successful. That's just what he's like. If you plugged him in you could power a small Scottish town with all of his energy."
The 'Why Does It Always Rain On Me?' singer also revealed the unique way he bonded with 'Yellow' hitmaker Chris after their partners gave birth to sons at the same time.
He added to Britain's Times newspaper: "He helped me reconstruct my tepee. I'd bought one on a whim and it pretty much took up our whole garden.
"Anyway, I'd taken it down and forgotten how to put it back up but Chris came round and we went on the internet and figured it out.
"We could've had the best YouTube moment ever - Chris Martin and Fran Healy constructing a tepee together."
Fran has a son Clay, two, with partner Nora Kryst, while Chris and wife Gwyneth Paltrow have two children, four-year-old daughter Apple and Moses, two.
