The father-of-two, 45, was spotted in The Green Room at the Gloucestershire race on Tuesday, with friend and TV presenter Natalie Pinkham sharing a beaming Instagram snap with Peter and Mike.
It’s not known if Peter was joined by his girlfriend, Lindsay Wallace, at the Festival. The couple made their public debut at the Epsom Derby last year.
Peter and former wife, Autumn Phillips, finalized their divorce in June 2021 after announcing their separation the previous year.
The pair, who were together for 12 years, share two daughters, Savannah, 12, and ten-year-old Isla.
Businesswoman Autumn stepped out with her new beau, Donal Mulryan, founder of the UK development and construction company Rockwell, as she attended the Cirencester horse trials with her daughters last March, with a source saying at the time: “They were enjoying a family day out at Cirencester.”
The entrepreneur was previously managing director for SEL UK, a boutique sports management company.
