Minogue, who is celebrating her 25th year in the music industry, is expected to perform orchestral versions of her greatest hits.
Late last year Minogue recorded her best known songs with a full orchestra at Abbey Road Studios in front of a live audience. A CD of the session is expected to be released later this year.
The classy headlining spot comes on the heels of Minogue’s surprise anti-tour earlier this year that saw her play B-sides and rare tracks in intimate venues.
BBC’s Proms in the Park is in London’s Hyde Park on September 8.
