King has been tweeting the Irish singer following his appearance on the ITV1 talent show. O'Shaughnessy captured the public's imagination with his romantic ditty 'No Name' and won a spot in the final last night (May 10) after performing another original song 'First Kiss'.
Speaking backstage at rehearsals about a potential blossoming romance with the Saturdays pop singer, O'Shaughnessy said: "She told me that she'd give me a date if I wrote a song for her. So I've started working on that already!
"Would I like a date with her? Of course I would, she's a beautiful girl. Writing a song for her won't be a problem."
On last night's Britain's Got Talent, Katie Lucia Keegan - the girl who Ryan wrote his 'No Name' song for - phoned in to reveal that she would not be able to date him because she currently has a boyfriend.
O'Shaughnessy is one of ten finalists confirmed to perform in tomorrow's (May 12) two-and-a-half-hour finale. They will be joined by one extra wildcard act, who has been selected by the judges from the losing semi-finalists.
