Grant became involved in the Bloomsbury Group, where he made many such great friends including Vanessa Bell. He would eventually live with Vanessa Bell who, though she was a married woman, fell deeply in love with him and, one night, succeeded in seducing him; Bell very much wanted a child by Grant, and she became pregnant in the spring of 1918. Although it is generally assumed that Grant's sexual relations with Bell ended in the months before Angelica was born (Christmas, 1918), they continued to live together for more than 40 years. During that time, their relationship was mainly domestic and creative, they often painted in the same studio together, praising and critiquing each other's work.
