Pattie Boyd reveals love triangle with Clapton and Harrison. Boyd has her letters containing her'secrets' from that period up for auction at Christie's.

In one of these, written by Clapt on in 1970, when Boyd was still the wife of the Beatles star, the famous guitarist asks if she still loves her husband and if she has another lover. In other letters it is instead Harrison, during a tour with the Beatles, who writes to her wife, asking her how he is and reminding her that he loves her.
