Oscars 2012: Cameron Diaz 'Banned' From Madonna's After Party By Demi Moore

The height of Hollywood royalty partied following Sunday night's Oscars but it seems one star was left out in the cold - Cameron Diaz was reportedly banned from Madonna's afterparty.

Material Girl Madonna threw her traditional bash after the 2012 Academy Awards and the shindig was set to be a star studded affair with A-listers including Angelina Jolie, Brad Pitt, Tom Cruise and Tom Hanks on the guest list.

However, Charlie's Angels star Cameron was banned from setting foot in the door - at the request of her former movie co-star Demi Moore.

Demi, who is currently recovering after receiving treatment for exhaustion and stress, has co-hosted the celebration in recent years and allegedly scrapped Cameron's invite after ex-husband Ashton Kutcher was spotted flirting with the actress at a Golden Globes party in January.

Speaking to The Mirror, a source said: "Demi was instrumental in the guest list and told Madonna that there was no way in hell Cameron should be allowed over the threshold.

"As a result she has been blackballed, and security informed not to let her in under any circumstance."

Demi and Ashton ended their six-year marriage in November after Ashton allegedly cheated with a number of younger girls.

Cameron starred with Ashton in 2008 comedy What Happens in Vegas and also dated Madonna's ex Alex Rodriguez - chuck in some champagne and the party had potential to get messy!
