Let's hope Madonna has forgotten that fashion critique, Kylie! Minogue leads A-list front row at Material Girl's Hyde Park gig
Madonna ends gig 2 minutes before 10:30pm curfew after Sir Paul McCartney and Bruce Springsteen's Hyde Park concert was cut short on Saturday
Ex-husband Guy Ritchie rumoured to be in the audience

Just a few weeks ago, Kylie Minogue dismissed one of Madonna's costumes on her current MDNA World Tour with a 'no, no, no'.
So hopefully the comments won't come back to haunt the Australian as she joined a host of A-list stars at the front row at the Queen of Pop's London gig tonight.
Kylie, who was openly admitted to being a huge fan of the Material Girl, posed with designer Stella McCartney backstage ahead of the Hyde Park concert.

The duo were just two of a group of stars, including Madonna's ex-husband Guy Ritichie, who watched the singer's first UK gig of her MDNA World Tour.
Also spotted in the 'golden circle' in front of the stage was George Michael, Kate Moss, Naomi Campbell and U2 rocker Adam Clayton.
The open-air concert was the latest date of Madonna's 87-date tour, which started in Israel in May.

Still got it: The singer showed no sign of her 53 years in the full-on routines
The 53-year-old singer repeated her controversial performances that had been seen in other countries, including her gun-toting fight with a male dancer to the song Gang Bang.
After arriving on stage later than scheduled, her concert wasn't affected by the rain half-way through.
She shouted to the crowd: 'OK everyone, let's say a prayer. Rain rain go away!'

Other guests expected included Madonna's producer friend William Orbit, who tweeted earlier on Tuesday: 'Really looking forward to seeing Madonna in Hyde Park tonight!!! I'll be where the mixing desk is. (not doing any mixing!)… just is the ideal spot for sound and view. And I'll be signing along with everybody else! Let me know if you'll be there.'
Madonna's friend Ingrid Casares was also set to attend, tweeting: 'Madonna performing in Hyde park! Best place to watch on a beautiful London day.. #nothingbetter.'
Up close and personal: Fans who had paid enough got to stand in the Golden Circle and get close to their idol
Despite arriving late on stage, Madonna managed to end the show just two minutes before the 10:30pm curfew.
No doubt she didn't want a repeat of Saturday's gig at the same venue, when Sir Paul McCartney and Bruce Springsteen's performance was cut short after they broke the curfew.
Concert promoter John Probyn said ahead of the concert: 'It won't happen again. We've had lengthy conversations with Madonna's people. They contacted us. We've worked out with them what time she needs to go on stage to finish on time. That's all in hand.'
