Madonna has revealed she has a 16 inch blade hidden inside her walking stick.

The 61-year-old singer has been walking with the support of a cane since injuring herself on her Madame X tour, and is believed to have torn a ligament in her knee.

Madonna shared a video on Instagram which showed her unscrewing the handle of her ornate silver-topped cane and pulling out a long, razor-sharp blade as she jokingly threatened a bar-owner in Lisbon, Portugal to bring her his best wine.

She said: “We want the finest wine money can buy. Watch out. If you don’t give me good wine, this is what’s going to happen...”

Pulling out the blade the singer quipped: “Give me red wine. Or give me cash!”

The executive producer of Sunday's Billboard Music Awards is defending the decision to have Madonna pay homage to Prince, which has been met with some criticism online and sparked a petition. “Listen, I think everybody is entitled to their opinion and everyone can have their own opinion, but I will say that we are honored and could not be more excited for Madonna to be on the show and to pay tribute to someone that was her friend and her peer and her colleague,” Mark Bracco said in an interview with The Associated Press on Tuesday, May 17, 2016. “I think it’s going to be fantastic.” (AP Photo/Kin Cheung, File)

Madonna was due to arrive in the UK to perform her first show at the London Palladium on Monday night, but she cancelled the performance - the ninth cancelled show on the tour so far - due to ill health.

The Borderline singer will have to find a new walking stick for her time in the UK, as it is illegal to carry a concealed weapon, or indeed any knife in public unless it has a folding blade with a cutting edge 3 inches long or less. The penalty for carrying a knife in the UK can be up to four years in prison.

Madonna left fans devastated on Sunday when she cancelled her Lisbon tour date with just 45 minutes notice. An email was sent to ticketholders at 7.45pm ahead of her expected appearance on stage at 8.30pm.

Announcing the cancellation of her first UK performance Madonna said: “As you all know, I have injuries that have plagued me since the beginning of the tour but I must always listen to my body and put my health first.”

Ticketmaster, which sold the tickets for the shows, said it had already issued refunds.

The next show is expected to go ahead at the London Palladium on Wednesday, 29 January.
