While crack-smoking Toronto Mayor Rob Ford may be in rehab trying to forget his days of hitting the pipe, wetting his whistle with booze or berating his constituents, his decision-making skills clearly still need a lot of work.

The generous politician lent his black Cadillac Escalade to his rehab buddy LeeAnne McRobb, 36, and she wound up getting arrested Tuesday for alleged DWI in the SUV, the Toronto Sun reports.

McRobb was a fellow resident at the GreenStone Muskoka treatment center, sources told the Sun.

She refused to explain why she was driving the disgraced politician’s car when confronted by two reporters at the impound lot in Gravenhurst, Ontario.

“It doesn’t matter. That’s for me to know,” she said in one of two videos posted on YouTube by MooseFM Wednesday. “You guys don’t need to know.”

It is not clear how close a relationship Ford has with McRobb, but she jokingly tells the man working at the impound lot that she left her watch in Ford’s room at the treatment facility.

“Not having a watch is not good. I’ve got a really nice one, too. I think I left it at GreenStone — maybe it’s in Rob Ford’s room, my watch, but whatever,” she says, shrugging it off eventually, saying that she’s “just kidding.”

A report from the Ontario Provincial Police confirmed that McRobb was stopped by police at 2:34 p.m. Tuesday and charged with impaired driving, according to the Sun.

McRobb said Ford was doing “top notch” in rehab but refused to comment further about him.

Ford’s lawyer Dennis Morris was relieved to hear that the mayor wasn’t involved in the drunken driving incident.

“I have not spoken to him, he’s in rehab as far as I’m concerned,” he told the Sun. “There is no allegation [Ford] was behind the wheel — that’s good news.”

Ford has been staying out of the public eye during his rehab stint, although he was spotted last week at his country cottage.
