Is Madonna Gwyneth Paltrow's 'frenemy'?

Taking an indirect jibe at Madonna, Gwyneth Paltrow has posted an obscure message on her website Goop.com in which she has blasted a former pal, whom she called 'frenemy', for turning against her.

Although the actress has kept the name under wraps, gossip-mills are running as to whom she's referring to as "frenemy".

"This person really did what they could to hurt me. I was deeply upset, I was angry, I was all of those things you feel when you find out that someone you thought you liked was venomous and dangerous. I restrained myself from fighting back. I tried to take the high road," Contactmusic quoted Paltrow as writing in the online newsletter.

She added: "But one day I heard that something unfortunate and humiliating had happened to this person. My reaction was deep relief and...happiness. There went the high road."

Signing off, Paltrow asked the readers: "So, why does it feel so good to hear something bad about someone you don't like?"
