The singer organised a party at her place in New York to show off her boyfriend A-Rod. According to FemaleFirst, this enraged her ex Guy Ritchie.
A source stated, "It is a massive slap in the face for Guy. Both he and Madonna share a lot of mutual friends who they still keep in touch with. Guy found out through one of them about this party and was pretty annoyed. He thought it showed a great deal of disrespect to him."
Madonna and Ritchie announced that they were divorcing last month after eight years of marriage.
