The British pop singer was riding on the London Underground when he spotted 28-year-old Juliet Oldfield, and after striking up a conversation with her, he asked her out on a date.
Oldfield tells Britain's Mail on Sunday newspaper, "First of all, I couldn't believe Jason was travelling on public transport. Then, I couldn't believe the attraction was mutual. A glance turned into a smile, then a hello, then a conversation. It was highly charged! He asked for my number and I gave it."
Orange was previously linked to British comedienne Catherine Tate.
