New York, June 29 : Oprah Winfrey's strong support for US presidential candidate Barak Obama seems to have incited a cold war between her and former US President Bill Clinton.
If sources are to be believed, Winfrey and Clinton didn't seem on good terms at Nelson Mandela's 90th birthday celebrations in London.
"There was a very cold reception between them," the New York Post quoted a source as saying.
When Winfrey went over to Mandela's table, where Clinton was seated, "Oprah and Bill, who used to be very close, barely acknowledged one another," the source added.
However, sources from Clinton and Winfrey camps claimed that the two spoke to each other at a private reception before the dinner.
The list of guests included Robert De Niro, Elton John, Neil Diamond, Kim Cattrall, Pierce Brosnan and Uma Thurman.
