Here’s a video of Dave’s interview with sluggers Derek Jeter, Andy Pettitte, and Jorge Posada.

According to The Wrap, NBC’s veteran crime drama — now in its 20th season — is currently casting for an upcoming episode that will revolve around a “well-known celebrity talk-show host, married with children,” who has engaged in “a series of short-lived affairs with some of the employees on the show and up until now has managed to keep them off the radar.”

Last month, an extortion plot forced Dave to admit on-air that he has had sex with a number of women who work for him.

Nell Scovell — who created the hit TGIF series Sabrina, The Teenage Witch — worked on Late Show for a year, before going to write for Charmed and NCIS. She says a number of women romantically-linked to Letterman wielded an unfair amount of power over other employees, creating a chilly climate behind the scenes. “Did I believe these female staffers were benefiting professionally from their personal relationships? Yes. Did that make me feel demeaned? Completely,” Scovell writes on VanityFair.com.

Scovell doesn’t confirm direct knowledge of Letterman’s sexual relationships, but says she was “aware of rumors.” Scovell writes, “Dave summoned me to his office and pressed me on why I was quitting the show. I considered telling him the truth, but with Dave’s rumored mistress within earshot, I balked.”

She says she’s speaking out for the first time because she wants “Dave to hire some qualified female writers and treat them with respect.”

“Now, I don’t want a lawsuit. I don’t want compensation. I don’t want revenge. I don’t want Dave to go down,” she says.

Here’s something we could go our entire lives without seeing — The David Letterman Sex Tape. We’re still recovering from the one with Mini-Me.

Better break out the Brain Bleach, ‘Crunchers, because we hear the scandal-plagued talk-show host has been rocked by yet another tawdry bombshell – reports of a sex tape showing him doing the mattress mambo with a “much younger” female staff member.

“Dave apparently didn’t know the location of the security cameras at his Late Show studio.”

Late Show snoops tell The National Enquirer, studio surveillance tape caught the 62-year-old comic in a series of — er — “compromising positions” — with a petite twentysomething he met as a staffer. Unfortunately for The Davester, the X-rated flick could play a key role in the trial of the 48 Hours producer accused of blackmailing him.

“If the tape makes its way into the criminal case, it’ll explode his marriage to smithereens,” blabs an insider. “It’s one thing for him to have publicly admitted to having had sexual relations with some women on his staff. It’s another to see him in the throes of passion with one of those women.”

Introducing Tales of the 24-Year-Old Virgin….

Earlier this month, the CBS late night comic was forced to confess to a string of affairs with at least eight female interns and staffers, following a botched extortion attempt. The news stunned officials at Quinnipiac University, who often send broadcast journalism majors to nearby New York City to intern on Letterman’s Late Show.

The college says it will tell staff in charge of placing interns to be particularly careful when sending students to the historic Ed Sullivan Theater.

“Due to recent circumstances we will have a discussion with those in charge of placing our interns at the David Letterman show in the future,” a rep from Quinnipac told TMZ.com overnight. “We will diligently oversee this internship program to ensure that our interns are out of harms’s way.”

GLOBE.

“Sex rehab will prove to the world he’s willing to change his cheating ways. But rehab for such a high-profile guy like Dave would be his worst nightmare.”

Dave hired the sharp Wake Forest alum in 1996. Stephanie later became Letterman’s right-hand woman, working as an assistant and often appeared on-air.

Late Show spies believe sex therapy would be the best way for the comedian to redeem himself publicly and in the eyes of his companion of 23 years, Regina Lasko — also a former staffer.

The couple got hitched last March.

A tipster tells GLOBE: “Dave’s been leading a dangerous, secretive life and it’s caving on him now…..With the extortion attempt, it’s all come out. He’s been having sex with women who work with him on the show for years — there could be eight or more.”

The gap-toothed 62-year-old is a serial cheater who needs treatment, pals say.

“He needs serious rehab if he wants to save his marriage and stop his self-destructive behavior,” says a second source. “People behind the scenes at the show have known for years he’s a serial cheater. Now he needs to do something drastic to show everyone he’s paying penance for his sins.”

What do you think? Does Letterman need professional help?
