from www.nydailynews.com – An ex-“Late Show” intern unmasked herself Saturday as one of David Letterman’s former flings – and sources revealed the randy funnyman keeps a bachelor pad atop the Ed Sullivan Theater.

“I was madly in love with him at the time,” said Holly Hester. “I would have married him. He was hilarious.”

The NYU alum, who it appears went on to become a top Hollywood producer, told TMZ.com that the relationship started in the early ’90s when Letterman called and asked her on a date to the movies.

A year-long, secret romance ensued, she said, until the funnyman called it off because of their age difference.

Outside what is believed to be Hester’s country home in Sebastopol, Calif. – in ritzy Sonoma County – a middle-aged man lashed out at a Daily News reporter last night. “Get the f— out of here. We’re being offered a lot of money for this s—,” he said.

He then hopped in a gray SUV and floored it up a half-mile long driveway leading to the home. Hester did not emerge.

The IMDB database shows that a Holly Hester is a veteran TV producer who has worked on a string of hit shows, including “Ellen,” “Drew Carey,” and “Grace Under Fire.” It was unclear if she is the same Hester, but public records also show a Holly Hester is married to an experienced TV graphics guy who once worked for Letterman.

The Hester quoted by TMZ made the stunning admission as a Letterman show source dished that he kept a secret bedroom above his set in the Ed Sullivan Theater on Broadway. “He doesn’t have to come out,” a staffer said. “He has a suite upstairs.”

An ex-“Late Show” staffer said Letterman kept a room insiders dubbed “the bunker” that was open only to his favorite young female underlings.

Letterman, 62, admitted on the air Thursday that he had had several affairs, apparently while dating longtime love Regina Lasko, who he married in March. The two have a son, Harry, 5.

A longtime assistant said he had the ability to cast a spell on the ladies.

“I don’t think women ever get over Dave,” Laurie Diamond told London’s Daily Telegraph.

A woman identified as a former paramour, Stephanie Birkitt, 34, remained in hiding Saturday. She was, until recently, dating Joe Halderman, who was arrested Thursday for allegedly threatening to go public with Letterman’s dalliances unless he was paid $2 million.

A “Late Show” office worker in 1997, Birkitt quickly developed a role as Letterman’s Girl Friday. She went on to appear in several skits as his comic foil. Behind the scenes, their relationship became intimate, sources said.

“The creepy relationship that Letterman maintained with Stephanie was obvious and not normal,” an insider said. “She was able to do anything and everything … It was pretty well known that Stephanie was the one that Letterman was having fun with.”

In numerous interviews, Birkitt gushed about Letterman, calling him “the greatest boss I could ever have.”
