Rachel tells us she just broke up with baseball star Bret Boone, days after Tiger called it quits with Lindsey Vonn.
So the question ... does Mistress #1 still have a hankerin' for the golfer with a roving eye?
Sources close to Rachel say she told them, "We both loved each other very much," but adding, "It was humiliating and devastating to have to break up that way."
Now the opening ... Rachel says, "He would have to do some major apologizing to get back in my good graces, that's for sure."
No word from Tiger, but remember, when he was banging Rachel he was at the top of his game.
