Oscars: Former Supremes members Diana Ross, Mary Wilson have awkward run-in: report

Diana Ross reportedly had an awkward run-in with former Supremes group member, Mary Wilson, at Elton John's AIDS Foundation's annual Oscars viewing party on Sunday night.

Page Six's Richard Johnson reports that the legendary diva, along with her son, Evan Ross, walked over to Quincy Jones' table at the exclusive soiree to say hello, but didn't realize that her former adversary Wilson was at the table, too.

"Diana looked like a deer caught in the headlights," Mark Bego, Wilson's ghostwriter on her tell-all "Dreamgirl: My Life as a Supreme," who was at the table, told Johnson. "Mary had a smile on her face."

Actress Lorna Luft was also at the table, and she quipped, "Okay kids, get to the bunker. This is going to be explosive."

Though the group anticipated that there could be drama when Ross and Wilson's paths collided, their interaction ended up being nothing but cordial. After Wilson greeted Ross, the two hugged and posed for a photo together with Jones.

"She 100 percent knew Ms. Wilson was at the table, that is why she went over," Ross' publicist said. "It was a really nice moment."

The interaction follows years of the two feuding on-and-off. Wilson wrote in her aforementioned memoir that she blames Ross for forcing third original member, Florence Ballard, out of their group in 1967. Ballard, who was replaced by Cindy Birdsong, died of a heart attack nine years later in 1976 after battling alcoholism, poverty and depression.

Another major point of contention for Wilson and Ross came in 1983 during Motown's 25th anniversary celebration, Motown 25. Before performing "Someday We'll Be Together," Wilson said that the Supremes only had 15 minutes to rehearse the number and she wasn't aware that Ross would introduce Motown founder Berry Gordy while they were onstage.

Not only that, but during their performance, Ross had grabbed the microphone from Wilson's hand.

"All I knew was Diana said, 'Hey, Berry. Come on down.' I said, 'Yeah, Berry. Come on down.' Me and my crazy self that I am, I enjoyed the moment," Wilson said. "I said certain things and I wasn't supposed to say those things, because they had plans. That disrupted the program. I am sorry to say it happened, because it not only spoiled my moment, but it spoiled The Supremes' moment of coming together, and we weren't able to finish our song."

Years later, plans for the Diana Ross & the Supremes: Return to Love tour blew up in 2000 when Wilson found out that Ross was set to be paid $15 million to her $4 million for the unlikely reunion tour. Wilson would go on to drop out of the tour, and Ross opted to perform several dates with other former members of the group, but half the dates were canceled after attendance plummeted.
