Why is Adele banned from hanging round with Rihanna?

Adele has banned herself from hanging out with Rihanna the night before she plays Glastonbury – in case she gets stoned and loses her voice.

We told over the weekend how the singer had confirmed her Saturday night headline slot during a gig on Friday night at London’s O2.

The following evening on stage, Adele told fans she had been forced to rule out a night out at Rihanna’s Wembley gig in June, because it will take place mere hours before she is due to perform on Worthy Farm.

And she’s a bit worried about accidentally passive toking on the night.

“I love her,” Adele says. “I’m thinking of going to Coventry to watch Rihanna because she’s playing Wembley the day before I play Glastonbury, and if I go to that, I’ll have no voice, I know it. All that weed in the air – I’ll get stoned.

“But I love her, honestly, all of that new album I love. I gotta try and go see her.”

RiRi, 28, plays Coventry the same day Adele takes to the Pyramid stage, so logistically, it sounds a bit tricky for Adele to hot foot it across – but the singer could easily make it to Glasgow or Manchester the following week. Adele has been vocal about her nerves about playing the 175,000 size crowds at Glastonbury, admitting: “The crowds are too big – I don’t know if I could do it.”

However, despite batting away suggestions she would play, the singer will attempt to combat her nerves on June 25th.

Last week, Adele, 27, told fans she had put herself on a strict diet to avoid damaging her voice. She gave up smoking in 2014.

The singer suffered a vocal haemorrhage in 2011 and required surgery on her vocal chords, which saw her forced to shelve the rest of her tour
