Diana Ross To Appear On '20/20'

Supremes lead singer will respond Friday to charges made by former bandmate Mary Wilson on earlier edition of program.

Singer Diana Ross will appear on the ABC-TV news program "20/20" at 10 p.m. EDT on Friday (April 21) to respond to criticism from her former Supremes bandmate Mary Wilson, according to the television network.

Ross will launch a summer Supremes reunion tour that will not include Wilson, the only other surviving member of the '60s group's original lineup.

Wilson, who reviled Ross on Thursday's edition of "20/20," has said that Ross shouldn't have used the Supremes' name without her participation.

"If there's going to be a reunion, I'd have to be in it," she said last month.

Instead of Wilson and longtime member Cindy Birdsong, who replaced late founding member Florence Ballard, Ross will tour this summer with Lynda Laurence and Scherrie Payne, two singers who joined the group after Ross left in 1970.

The original Supremes lineup recorded a string of hits in the '60s, including "Stop! In the Name of Love." Ross was the only Supreme singing on the group's last #1 pop and R&B hit, "Someday We'll Be Together" (RealAudio excerpt). It also was the last song Ross recorded with the group before she left.
