Actor and musician Jason Donovan has once again proved he's a good egg - rushing out last night in just his underpants to help put out a fire at a neighbour's home.

Fortunately JD had an extinguisher handy and he was on the scene in seconds, having spotted flames across the road. Hot on his heels were the London Fire Brigade who put out the blaze.

Playing down his near-naked heroics, Jason tweeted: "This is a good reason to always wear PJs to bed (in case of emergencies) but much more importantly to have fire extinguishers at hand in the home."

What he doesn't say is that if you're heading unexpectedly outdoors in your boxer briefs, make sure they're up to public scrutiny because there's always someone around with a camera.

You know Mother always told you to wear clean pants JUST IN CASE. So in case you're called upon to go outdoors in your undies, DGU suggests being ready with HOM's HO1 Boxer Brief
