London: Beyonce and Oscar-winning actress Gwyneth Paltrow's friendship has reportedly gone sour owing to the R&B star's growing friendship with Madonna.
The "Drunk in Love" hitmaker is in Paltrow's bad books at the moment as she's been growing close to the actress' former best friend after appearing in her latest music video, reported Female First.
"Beyonce and Gwyneth are not friends at the moment. Beyonce's staff have been openly discussing it. Gwyneth hasn't been happy with how close Beyonce and Madonna have become.
"It was especially annoying to her that Beyonce appeared in Madonna's last video. It's a case of 'the friend of my enemy is not my friend'," a source said.
Beyonce, 33, and Paltrow, whose ex-husband Chris Martin is friends with the singer's husband Jay Z, had been very close in the past.
