Britt had by then moved to Los Angeles, where she began living with music producer Lou Adler, and they had a son together named Nicolai in 1973. But her relationship with Lou ended after she discovered that he was cheating on her. Britt's most famous love affair with a rock star was with Rod Stewart, whom she began dating after her affair with Lou Adler had ended. Rod and Britt eventually lived together but the relationship ended after Britt found out that Rod was unfaithful to her. The lawsuit was dismissed by the courts.
Britt now keeps a very low profile and has basically retired from acting.
