It seems that an anonymous female source claims that Christina slept with women during her marriage.
Moreover, the source said: “The bodyguard told me it was an understanding within their marriage and that she brings girls home and Jordan’s okay with it,” said the source.
“I met Christina in the bathroom and she told me she liked to play with girls. I ended up not pursuing anything with it because the situation just seemed so weird to me, but Christina was definitely looking to hook up.”
Therefore, Bratman got jealous and this led to divorce from Aguilera.
