Mel Gibson's defense to this new claim might be to insist he did not, in fact, promise her a rose garden:

In all fairness, that could be a metaphor; he could have meant "I will give you permanent residence in a very pleasant, aromatic place. He also said - metaphorically! - he would burn down her house, but perhaps he was just in a jolly mood, singing a Talking Heads tune. Reached for comment, Gibson picked up a butcher knife and disemboweled the reporter, shouting "You're not even good enough for the rosebed! You're going under the geraniums!"

(Note from the Dept. of Obviousness: that last part was false.)
