  • Bill Clinton says ABC reached out to him to appear on Dancing with the Stars but his schedule prevented him from mamboing with the likes of Petra Murgatroyd. "This is interesting," the former president said when the subject came up during an appearance on Rachael Ray's TV show Tuesday. "Actually, they contacted me once about this. And I told them I didn't have the time to train for it. You know you actually go out there and you train, you really work at it. So I had to pass. But I think it's a hoot." [E!]

  • In May, a man named Nader Sharif sued Mel Gibson, claiming the actor "swindled" him out of $200,000 by convincing him to invest in a "recyclable rubber company" called--what else?--Green Rubber. In a new series of court documents filed Tuesday, Sharif also claims Gibson tried to run him over with his car in July "after the two ran into each other at a Costa Rican bakery." According to Sharif's account of the incident, Gibson swore at him, and told him to get out of town. The unpleasantness continued outside the bakery as Gibson, now behind the wheel of his car, "accelerated..to a high rate of speed," all while reportedly giving Sharif him the finger. A witness to the incident says Gibson was just in the Costa Rican bakery enjoying "a sweet pastry" when Sharif showed up and started haranguing him. When the actor did believe, the source says Sharif did follow him, but Gibson didn't drive anywhere near him. [TMZ]
