Cable television mogul Ted Turner has bought an engagement ring for Oscar-winning actress Jane Fonda and they are expected to announce their engagement in December.

A source at Cable News Network, which Turner owns, told The Atlanta Constitution that Turner, 51, will give the ring to Fonda, 52, on Dec. 21, her birthday, although the couple has not set a wedding date.Fonda's publicist told reporters the wedding probably will take place sometime after Fonda's son, Troy Hayden, graduates from high school this coming summer.
