Madonna hosted her annual Oscars party at her manager Guy Oseary's mansion, and onlookers were reportedly stunned to see Ashton Kutcher, the ex-husband of Demi Moore, in attendance.
Moore, 50, and Madonna, 54, were previously best friends until the actress separated from Kutcher, 34. An insider claims that Moore was not invited to Madonna's star-studded Hollywood party because the singer sided with the "Two & A Half Men" star.
"Madonna is firmly on side Ashton. She adores him and thinks that out of him and Demi he's the one with the glittering career," a source told RadarOnline.com.
"Madonna loves having Ashton around as he's great eye candy, he's funny and he flirts outrageously with her — In Madonna's eyes, there's no competition – when it comes to picking sides Ashton is the obvious winner!" the source went on.
Kutcher, who has since moved on with actress Mila Kunis, filed for divorce from Moore after six years of marriage just days before Christmas. Madonna, who has previously invited Moore to her annual bash, stunned her guests by inviting Kutcher and snubbing her once close friend.
"When Ashton walked in it got the crowd buzzing! Madonna's never spoken about the split, but it's obvious she's sided with him over Demi," the confidante said.
"It was kind of shocking as Demi has even hosted the party with Madonna in the past, so it's even more of a mega snub! Madonna clearly loves Ashton though, they were dancing together a lot throughout the night and flirting up a storm!" the source explained.
Moore, who has kept a low profile since Kutcher's 2011 cheating scandal, was reportedly blindsided by his divorce filing, despite initiating their split. The twice-married actress was hoping that she and Kutcher could settle their financial matters to avoid having settlement details leaked to the press. according to The New York Post.
"Demi had hoped to negotiate a financial settlement quietly and then file paperwork afterwards to show the matter had been settled," a source previously told The Post's Page Six.
"Demi was asking for so much money, and [the negotiation] was dragging on so long, that Kutcher got fed up and filed papers, which means their divorce negotiations will become more public," the source said.
