The woman who inspired The Beatles' "Lucy In The Sky With Diamonds" has died after battling the immune-system disease Lupus, according to the BBC.

Lucy Vodden, who was 46 at the time of her death, was a nursery school classmate of John Lennon's son Julian. Despite the rumored LSD references, the song apparently was written after Julian brought home a picture he had drawn of his young friend, telling his dad: "It's Lucy in the sky with diamonds."

Vodden and Julian Lennon reportedly had resumed their friendship in recent months after he learned of her illness.

In a 2007 BBC radio interview, Vodden confirmed she was the subject of the famous song. "I remember Julian and I both doing pictures on a double-sided easel, throwing paint at each other, much to the horror of the classroom attendant. Julian had painted a picture and on that particular day his father turned up with the chauffeur to pick him up from school."

Julian and his mother, John's first wife Cynthia, were "shocked and saddened by the loss of Lucy and their thoughts are with her husband and family today and always," the St. Thomas' Lupus Trust Charity said in an official announcement. The trust had been supporting Vodden and her husband during her illness, according to the BBC report.
