What was the name of Picasso's mistress who was the subject of 'Le Rêve'?

What was the name of Picasso’s mistress who was the subject of “Le Rêve”? Her name was Marie-Thérèse Walter.

Picasso painted “Le Rêve,” or “The Dream,” in 1932, portraying Walter as a young woman reclining in a red armchair. She was one of the central muses of Picasso’s early-1930s work, a period marked by rounded forms, bold colors, and dreamlike distortions.

Walter met Picasso in Paris in 1927, when she was seventeen and he was still married to Olga Khokhlova. Their relationship remained secret for years. She became the mother of Picasso’s daughter, Maya, born in 1935, and inspired numerous paintings, drawings, and sculptures.

The other names in the quiz are also associated with Picasso, which makes this question easy to confuse. Olga Khokhlova was his first wife, Dora Maar was a later partner and artist, and Françoise Gilot was his partner after the Second World War. “Le Rêve” specifically depicts Walter.
