The athletics showpiece will take place in Glasgow, Scotland later this month with a closing ceremony at the city's Hampden Park football stadium to be held on 3 August.
A source tells The Sun newspaper the Spinning Around hitmaker will perform a five-song set at the event, adding that the singer hopes the appearance will boost her music career.
The source says: "Kylie is putting all her eggs into one basket. She was delighted when her management pulled off this high-profile concert.
"Although she's huge in the UK and elsewhere, she's never fully managed to achieve global status like Beyonce and Rihanna."
