Julie Postle, previously known to gossip hounds as “Unidentified Orlando Cocktail Waitress,” was identified as one of Tiger Woods’ mistresses this afternoon.

That makes 10 according to THG’s updated, official Tiger mistress list.

Jules was outed by ex-beau Brian Kimbrough, who claims she was seeing Tiger Woods on the side in 2004 while he was casually dating the blonde cutie.

Brian says Tiger called himself “Mr. Brightside” in reference to a Killers’ song about a jealous lover, and the golfer would call up Julie Postle “incessantly.”

“One time, her phone rang, and it said a weird name on it – ‘Mr. Brightside,’” Kimbrough recalled. “And I was like, ‘What the hell is this?’ She smiled.”

“She just said it was Tiger but didn’t answer it. But she played me the voice mail. It said, ‘Hey, it’s Tiger, just seeing how you’re doing. Give me a call.’”

Why’d Kimbrough stay with Postle, if she was fooling around with Woods?

“She was hot,” he said.

There’s small bright side now for Julie Postle’s former fling.

Kimbrough says Woods even invited Postle to Vegas and said, ‘If you break up with your boyfriend, I can give you some money to get you on your feet.’”

Don’t tell that to Jamie Jungers.

Things later got more serious between Kimbrough and Postle, and she said she and Tiger weren’t speaking anymore. But we know how that goes.

The mother of Postle’s former roommate, Morgan Coles, backs up the tale.

“Tiger was obsessed, really hunted her,” Nola Coles recalls. “He used to go into Roxy demanding Julie. ‘Where’s Julie? I want to see Julie.’

“She was 20 then, and I said, ‘You’ve got to get a condo out of this,’” the mother said, “and she just said, ‘Oh, no, I can’t do that to Tiger.’”

Naturally, Julie Postle’s trysts and phone calls with Tiger Woods, which started in 2004, continued even after he was married to Elin Nordegren.

Also naturally, “Tiger told Postle that his marriage was just for publicity. She said it was for his image, entirely for the media and wasn’t real.”

Hope you’ve got a excellent divorce lawyer, Tiger.
