Olivia was working at A&M Records as a secretary, that's when she met George. A&M were distributing George Harrison's Dark Horse label, it was 1974 when the two met at a party and would soon spend their time talking over the phone. The two soon found out they had a lot in common and she was then invited on George's 1974 American Tour where they really started their relationship. The two are said to have wanted to get married as soon as George's divorce with first wife Pattie (read about her here ) were final. It was in 1977 when Pattie and George's divorce was finalized. Olivia soon found out she was pregnant and had their first and only child, Dhani on 1 August 1978. The couple were then married the following month on 2 September, Joe Brown was best man. The family lived in George's home at Friar Park.
Olivia inspired George's writing including his songs "Dark Sweet Lady", "Soft Touch", and "Beautiful Girl" a song he had started writing with Pattie but changed it to be about Olivia.
