Madonna will miss her own post-Oscars party. The hitmaker is reportedly likely to ditch her own annual post-Academy Award show celebration in favour of rehearsing for the BRIT Awards 2015, which take place in London next Wednesday. A former guest shared: "People go to the Vanity Fair party to be photographed - then they go to Madonna's to party in private." The party may be Hollywood's hottest celebration but some people are "annoyed" that her party is so exclusive. A source added: "Madonna's managed to usurp the Oscars, and she's not from the film business. "Some people are annoyed that her party has skimmed the most famous people from the top." Meanwhile, the next few weeks will see the singer begin her promotion for her upcoming album and her representative has cited this as the reason for missing her own party.
