ITV daytime presenter Lorraine Kelly has admitted to never taking off her bra, which has sparked a heated debate about the medical advantages.

The Scottish presenter, 59, caused a "storm in a G-cup" after making the 'throwaway' remark to Loose Women's Coleen Nolan.

Lorraine reacted to the sensation over her admission on her show and asked Dr Hilary if she was "strange", the Mirror reports .

Speaking on her show on Thursday morning, Lorraine said: "Yesterday on the show I made a very innocent remark to Coleen Nolan. We were talking about bras. 24 hours on and people are still talking about this. It was just a throwaway remark."

The presenter joined Dr Hilary Jones and fashion expert Mark Heyes to discuss the topical issue.

Lorraine said: "Hilary I keep my bra on, but obviously if I’ve slept in it overnight I change it every day. Of course I do. "Is there anything wrong with sleeping in your bra? Am I strange?"

The show's resident medic, Dr Hilary, said there is actually no benefit or disadvantage.

Dr Hilary said: "There is nothing to suggest there is any medical benefit or disadvantage.

"I can imagine why some women, for comfort, would keep a bra on at night but there is no other reason.

"When you are standing, there is a gravitational pull and things can go south but when you are in bed, you are horizontal and nothing should be happening."

But Lorraine wasn’t convinced, adding: "I just don’t like being all loose."

'Wearing a bra has kept them perky'

Fashion expert Mark Heyes then weighed in by confessing he doesn't wear anything in bed.

Dr Hilary agreed: "Mark’s right, I don’t understand people who get dressed to go to bed. Pyjamas, what is that all about?"

Lorraine said: "Boys are funny like that. Boys like being naked. I like to have my nightie on."

Later, she added: "[My boobs] are not bad for a lady of my age. I think wearing a bra has kept them perky."

This comes after Lorraine announced that she doesn't take her bra off in bed.

Lorraine said: "I'm aghast because I keep my bra on all the time. I even sleep with it. I didn't realise that was weird.

"I said that this morning and everyone went 'What? What are you talking about?'."

Cupping her breasts, Lorraine continued: "I don't feel right when I take my bra off. It feels weird."

'Discussing the important news'

Lorraine viewers took to  Twitter  to give their opinions on the bra controversy.

One viewer said: "I honestly don't know how you can wear a bra in bed, I can't wait to take mine off at bedtime"

Another added: "Oh no I can't sleep with my bra it's uncomfortable."

Another viewer added: "Turns over to #lorraine and they are discussing the important news, wearing a bra in bed! Looks for large item to throw at TV."
