Sprawling on the floor of a lift looking hot and bothered, Sir Rod Stewart is clearly having one of those up-and-down days.

The star was getting some retail therapy at Prada with his son Alastair, 20, and Alastair’s girlfriend Mell Ratto, when the trio found themselves trapped in the store elevator – and clearly wishing they’d taken the stairs.

Despite the Maggie May singer being one of the world's biggest music stars – having sold more than 100 million records and earned two inductions into the Rock & Roll Hall of Fame – help was not immediately at hand.

Eventually, the trio gave up waiting, sat down on the floor and got in touch with Prada via Instagram with the understated plea: 'Can someone help get us out of the elevator?'

While being trapped in a lift is a nightmare for many, Sir Rod, 81, and company appeared more bored than panicked as they waited to be rescued during the drama last week.

Perhaps they were thinking of ways to describe their plight by reimagining some of the star's lyrics – Wake up Prada I think I got something to say to you (for instance).

It's the latest in a string of minor setbacks for the singer. In June, he was forced to use an oxygen tank during a concert in West Valley City, Utah, after almost fainting on stage, taking breaths from the apparatus throughout the remainder of the performance.

The drama came just a week after he cancelled a concert in California citing health concerns, only to fly by private jet to Boston 24 hours later to watch Scotland take on Haiti in the World Cup.

The decision did not sit well with fans who had been expecting to see him perform.

Most people would be happy to succeed in one career – but not Suki Waterhouse. Not only is she a supermodel, but she's also an in-demand singer, appearing on Friday at the Lollapalooza festival in Chicago in a Seventies rock-inspired outfit of tiny hotpants and pink, ruffled cape.

She has revealed several tracks on her third album, Loveland, were inspired by her Hollywood actor fiance Robert Pattinson – including Notting Hill, about the boujie flat where the couple fell in love, and one about missing the Batman star while he was travelling, called Weirdo. Now that's a pet name if ever there was one!

Forfet Dua Lipa… meet Tua Lipa. That's the nickname given to the star after her insistence on having tulips at her wedding in June.

The tulip season runs from March to May but that didn't deter Dua, 30, who held a huge wedding party in Sicily with actor hubby Callum Turner, 36.

'The flowers had to be imported at vast expense,' my source says. 'The wedding florists are calling her Tua Lipa.

Lila Moss looked every inch like her supermodel mother Kate in Ibiza last week, trying on feather mini-shorts and bejewelled corsets at trendy clothes shop Annie's Ibiza.

But my spies tell me Lila, 23, was without one usual accessory... her on-and-off boyfriend Yoni Helbitz.

'Lila has outgrown him,' my source tells me. The pair have already broken up and got back together once this year, but my source confirms: 'This time, it's for real.'

Do all wizards look the same? Fans often mix up Gandalf actor Sir Ian McKellen and the late Michael Gambon as Dumbledore.

Sir Ian recalls Gambon once admitting that: ‘They hand over their wretched 8x10 [photos] of you and I just sign your name.’

Congratulations to David Linley’s daughter Margarita Armstrong-Jones, 24, who has won a coveted spot at Mayfair’s Dover Street Market exhibition.

Princess Margaret’s granddaughter, who makes Matita Jewellery, has finished a tough course in her craft at Alchimia, in Florence.
