Well, he at least seems to be committed to long term relationships...

Richards maintains cordial relations with Italian-born actress Anita Pallenberg, the mother of his first three children. Richards and Pallenberg, who never married, were a couple from 1967 to 1979.
Together they have a son, Marlon Leon Sundeep (named after the actor Marlon Brando), born in 1969,[70] and a daughter, Angela (originally named Dandelion), born in 1972.[71] Their third child, a son named Tara Jo Jo Gunne (after Richards' and Pallenberg's friend Guinness heir Tara Browne), died on 6 June 1976 at just over two months old of SIDS (or, Sudden Infant Death Syndrome).[72] Richards was away on tour at the time, something which he said has haunted him since.[73]
Later in 1979, Richards met his future wife, model Patti Hansen.
They married on 18 December 1983, Richards' 40th birthday, and have two daughters, Theodora Dupree and Alexandra Nicole, born in 1985 and 1986 respectively. In March 2014, it was reported that Richards was writing a children's book with Theodora, Gus and Me: The Story of My Granddad and My First Guitar. Theodora was reported as contributing pen and ink illustrations for the book, which was inspired by the man she's named after (Richards' grandfather Theodore Augustus Dupree).[74]
Richards still owns Redlands, the Sussex estate he purchased in 1966, as well as a home in Weston, Connecticut and another in the private resort island of Parrot Cay, Turks & Caicos.[75][76] His primary home is in Weston.[77] In June 2013, Richards said that he would retire with his family to Parrot Cay or Jamaica if he knew his death was coming.[78] Keith Richards has five grandchildren,[79] three from his son Marlon and two from his daughter Angela.[80]
He is an avid reader with a strong interest in history and owns an extensive library.[81][82] An April 2010 article revealed that Richards yearns to be a librarian.[83]
