Someone should buy Lindsay Lohan a watch that works — and then teach her how to use it!

The scandal magnet had hired celebrity photographers Markus Klinko and Indrani — stars of the upcoming Bravo show Double Exposure — to shoot the new ad campaign for her 6126 leggings line on Friday at Miraval Living, a luxury condo building on Manhattan’s chic Upper East Side… But then she managed to show up 10 hours late!

“The call time was at 10am, but Lindsay didn’t show up until 8pm — an hour after the scheduled 7pm wrap time,” a source from the set of the photo shoot tells OK!. “She just left a crew of over 25 people, just hanging around.

The source says that once she finally got there, Lindz “complained about the camera crews and requested a 12-pack of Red Bull,” says the insider, who added that the shoot finally wrapped around 2am Saturday morning.

While it’s possible that LiLo simply got her AMs and PMs mixed up, some are wondering if her late nights out in NYC during Mercedes-Benz Fashion Week might be wearing on her.

LiLo, who has just been named the artistic advisor to design house Emanuel Ungaro, had been spotted out the night before with execs from the company at the Minetta Tavern “looking sullen.” And then the actress was still up at 6am — only a few hours before she was supposed to be on set — Tweeting about on-off-on-off girlfriend Sam Ronson.

OK! has reached out to Lindsay’s rep for a comment.
