Former New York City Mayor Rudolph Giuliani proposed to his longtime companion, Judith Nathan, last week during a business trip to Paris, reports The New York Times. She said yes.

"They are ecstatic," a Giuliani spokeswoman tells the paper.

No wedding date has been announced.

According to the New York Post, the former mayor, 58, presented Nathan with a sapphire-and-diamond ring similar to the one Prince Charles gave Diana when they got engaged in 1981. (They divorced in 1996.)

"I don't know what size it was," Giuliani told reporters in Paris about the ring. "At some point you'll see it."

After a highly publicized and acrimonious test of wills, Giuliani became officially divorced from his second wife, actress and cable TV hostess Donna Hanover, earlier this year. They were married for 18 years and have two children, Andrew and Caroline, ages 16 and 13.

Giuliani's first marriage, to his second cousin, Regina Peruggi, lasted 14 years and was ultimately annulled, says The Times.

Nathan was previously married to Bruce Nathan, with whom she became embroiled in a nasty custody fight.
