Ohhhhhh wowsers. Someone backed David Letterman into quite a corner. The late-night host admitted at a taping of his show this afternoon that someone attempted to blackmail him for $2M as a result of sexual relations he’d had with members of his staff.

During the taping of his CBS late-night show in New York, Letterman discussed receiving a threat to either pay $2 million or risk the relationships being made public.

In a release from the show’s production company, Letterman said he referred the matter to the Manhattan district attorney’s office and that an investigation ended in an arrest Thursday. Letterman did not identify the person he said was arrested.

As part of the investigation, Letterman said he issued a “phony” $2 million check to the individual and the arrest followed — along with testimony by Letterman.

“This morning, I did something I’ve never done in my life,” said Letterman. “I had to go downtown and testify before a grand jury.”

In his testimony, he said he acknowledged sexual relationships with members of his staff. It was not immediately clear when the relationships took place; Letterman and longtime girlfriend Regina Lasko married in March. The couple began dating in 1986 and have a son, Harry, born in November 2003.

“My response to that is, yes I have,” Letterman said. “Would it be embarrassing if it were made public? Perhaps it would. I feel like I need to protect these people. I need to certainly protect my family.”

I’m going to go ahead and assume that the relationships took place while he was with his current girlfriend. If they happened before 1986, why would he feel threatened by a blackmail attempt? Who cares who banged whom in 1986? But obviously Letterman’s World Wide Pants are living up to their name. I’m waiting on a clip of the actual Letterman broadcast so I can embed it … let me know if you come across it on YouTube.

Update: Vid is above. Awwwwwkward. TMZ reports that 51-year-old Robert Halderman, an employee of 48 Hours, has been arrested, and CBS has suspended him pending results of the investigation.

When I found out our sponsor for this month was Carmex, I was delighted. I am, in actuality, a Carmex devotee, so I don’t have to make up something that sounds positive about a product I’ve never heard of. That’s a relief. I’m one of those girls who, starting at the age of about 5, went through around 30 jars of Carmex each winter. This year, they were kind enough to send me five samples of their latest product, Carmex MoisturePlus lip balm, which is basically Carmex in a lipstick tube. That should be enough to last me through mid-October. Seriously though it’s a way cool product, and I’m not sure why they didn’t think of it sooner. It tastes yummy and makes your lips tingle and works as well as any other Carmex product, but it’s less messy.

As a thank-you to Carmex for funding us this month (all together now: “Thank you, Carmex!”), we thought it would be fun to put together a couple galleries of celebrity lips. Carmex wanted to do a gallery of the hottest celebrity lips. And I was like, “Okay, we can do that, but only if I can accompany it with a gallery of the most botched celebrity lip injections.” Hee hee. I like to remain true to my craft. So we agreed to do both. You can check out the Luscious Lips Photo Gallery here, and the Hollywood’s Most Botched Lip Injections Photo Gallery here. Enjoy, and thank you again to Carmex MoisturePlus lip balm for keeping us in business!!!

Lindsay showed up tonight at a Vogue party in Paris, because she’s completely and totally stoned a fashion maven.  I’m pleased to see her not wearing leggings or flannel, but I’m horrified to see her 15 year old sister Ali “How Can Your Mother Let You Walk Out Of The House Looking Like That?” Lohan looking like a backup dancer that just stepped off a Robert Plante video shoot.  I can’t even discuss the dude standing behind the two of them.  He’s obviously the dealer a friend,

The paps are always looking to break a new story, so they made sure to get a close up of LL’s arm which shows some cutting scars and bruising as well.  I don’t know what’s up with Linds, but I hope she’s set down the razor blade and picked up a new lease on life.  Maybe while she’s picking up that new lease on life, she can pick up some Miss Clairol too.  Her hair is officially yellow.

“I used to have to dress up as a banana…I had the option of apple or banana. I always went with banana because it was thinner.”

Megan Fox in Nylon’s October issue interview.

Please, oh please let a picture of Megan Fox working at a smoothie bar surface.  I need to see her dressed as a Chiquita.  Also, is anyone working on a coffee table book of Megan Fox quotes?  Because I really think it would be a best seller … especially if you can get your hands on that banana pic.

She’s amazing.  Of course, when I say “amazing” you know that I mean “imbecilic”.

Brit has a month to kill before she heads off on tour to Australia.  What else to do except buy bedding at Target and a bird cage at the pet store?  See?  She’s just like us, y’all.  Just dressed sluttier more exuberantly and surrounded by a bodyguard, LAPD, security guards and a Target Soft Lines Team Lead.

Top Chef host Padma Lakshmi is expecting her first baby, an event she is calling a “medical miracle”.  Lakshmi is a co-founder of the Endometriosis Foundation of America as well as a long-time sufferer of the condition.

Padma hasn’t named the father yet, but I was wondering what was up when I saw her on the Emmy red carpet.  I figured she moved past eating just the garnish during Top Chef judging segments and had ventured into consuming actual entrees.

Congrats to Padma and the mystery daddy (who I’m sure is a billionaire)!
