The 10-day extravaganza at Hyde Park will see the Latin diva and the 'Hello' hitmaker close the ceremony that has performances by Bon Jovi, who will open the event, Elton John and the Rolling Stones, reported Contactmusic.
They will be joined on the main Great Oak Stage by funk legend Nile Rodgers, fronting his seminal dance outfit and many others.
Rob Hallett, spokesperson for a promoter said, "I can't think of a better way to close our event in Hyde Park than with Heart In The Park."
