The heart of the city centre will be transformed into a giant street party – and celebrations will last all day.
The Queen will be joined by the Duke of Edinburgh at the event on Wednesday, July 4.
Michelle, 31, said: "It's a big honour to be involved in Glasgow's Jubilee celebrations. There are a lot of other Scottish artists who could have been asked.
"We all saw the concert down in London and, while this obviously isn't going to be on the same scale, this is our version of events.
"The Queen isn't going to that many cities so it's pretty cool she's coming to Glasgow.
"I'll be calling Sean Batty to find out what the weather's going to be like."
As Glasgow takes its turn to celebrate the Queen's 60 years on the throne, Michelle will perform as part of a family entertainment day in the city.
She will be joined by a slew of performers including The X Factor's Gamu, the National Youth Choir of Scotland, the Red Hot Chilli Pipers and Jai McDowall.
The St Paul's Primary School Choir will perform and the dedicated youngsters from Whiteinch primary are busy practising so they are note-perfect for their big day.
Shea Campbell, 10, is one of the soloists in the ensemble and is coming back from his family holiday in Spain so he can take part in the performance.
The P6 pupil said: "I'm not nervous, I'm excited. My dad's coming back with me from Spain so I can do it."
Their piece, called the Glasgow Song, began as part of a Education Arts Initiative project with P7 pupils of the school in 2010, who wrote the song with the help from their teacher Lisa Brown.
Glasgow-based singer, songwriter and violinist Laura McGhee will be flying in from Nashville, where she has been performing, especially for the occasion and will play the violin alongside the kids.
A number of tribute acts – to Take That, Abba, the Beatles, Elvis Presley and Michael Jackson – will also be performing. The headliners will be Hue and Cry.
There will also be face painting, balloon modelling, horse-and-dray rides and the chance to have a picnic in the square.
Lord Provost Sadie Docherty, who will meet the Queen in her role as Lord-Lieutenant, said: "The Queen and the Duke of Edinburgh are always assured a wonderful warm welcome in Glasgow – and I'm extremely proud that they are to visit during this Diamond Jubilee year."
Mrs Docherty added: "Our event will be open to the public, with a real street party atmosphere and music and family entertainment throughout the day.
"I'm delighted that, having watched thousands take part in Jubilee events in London, Glaswegians will now have the chance to share their own celebrations with the Queen."
It will be the Queen's first visit to Glasgow since 2006 when she reopened the Kelvingrove Art Gallery and Museum.
The event is free. However, organisers say that if the square becomes too full they will operate a one-in, one- out policy.
