The Platinum Jubilee (of Queen Elizabeth II) was held in London in front of Buckingham Palace, so entertainer and singer Diana Ross sung her famous song there.

The night’s closer, Diana Ross, brought the crowd to their feet with a pumped-up version of “Aint No Mountain High Enough.” Celebration of the British Monarch’s 70th anniversary on the throne

The 78-year-old soul singer took to the stage in a white and black tiered dress, delivering soaring high notes backed by a grandiose orchestra.

The Platinum Jubilee concert was held  in United Kingdom by the BBC in honor to Queen Elizabeth II, who ascended to the throne on February 6, 1952.

After some viewers criticism, the BBC have denied that Diana Ross was miming during her performance at the Platinum Party at the Palace.

Ahead of her UK tour, Ross was the headline performer at the Platinum Jubilee event and closed the show at Buckingham Palace

There was a moment during the broadcast where Ross stopped singing to blow kisses at the crowd but the backing track containing her vocals carried on playing.

She was also seen adjusting her belt which contained a monitor. Musicians often use the monitors to hear themselves properly when performing.

The live audience also noticed that singer Diana Ross was out of tune during her performance of Chain Reaction.

The show marked Diana Ross' first performance in the UK for 15 years. The former Supremes singer is set to embark on a tour of the UK later this month.

The Upside Down singer  Diana Ross will be performing at a number of outdoor concerts at locations such as Longleat and Durham.
