Pornography

Karlie Redd must be gunning for fans of a particular porn fetish -- at least according to another 'Love & Hip Hop' star who says she's just too damn old to be having sex on camera.

Sincere Show ... from 'L&HH Hollywood' ... has heard all about Karlie's offer to get down and dirty for Vivid. She hasn't decided yet if she's gonna do it -- so he decided to give Karlie some advice.

Sincere's take is no-holds barred, hysterical ... and a little ageist. Karlie's official age is -- she doesn't have one. 'L&HH' fans estimate her range to be from 37 to 49.

A piece of Farrah Abraham can be yours … and we’re not talking about her ass -- the backdoor teen mom has put her DNA on the market.

Abraham's partnered with Celebrity Gene, a company that liquefies the DNA of celebrities -- usually extracted from hair -- and puts it in a vial you can wear around your neck. Very Angelina Jolie circa 2001.

The jewelry vials go for $99, and it’s mostly for a good cause because 50% goes to the charity of the celeb's choice – in Farrah’s case, it's Operation Underground Railroad, which helps rescue kidnapped children from slavery.

We're told Abraham's also banking a 10% cut from sales ... in addition to the roughly $30,000 she got upfront for the DNA sample.

Abraham has a history with the double helix … she tells TMZ a positive paternity test changed her life and "created a better future" (aka Social Security benefits) for her daughter.

Abraham joins the ranks of Michael Jackson, Princess Diana, Elvis and Al Capone, who also have DNA for sale via the site ... so pick wisely.

Karlie Redd has proven she's cool with showing off her assets, but now she's got an offer to go pro ... by starring in a XXX production.

We've seen the letter Vivid Entertainment sent to the "Love & Hip Hop: Atlanta" star ... offering her a chance to shoot two sex scenes.

If she accepts, Karlie's guaranteed $25k, but the real money comes on the back-end. We're told she has the possibility of making over six figures, because as the folks at Vivid know (Kim K, Courtney Stodden, Mimi & Nikko, Farrah Abraham) celeb sex tapes tend to be profitable.

Karlie will have to go all in though. The offer requires her to follow in Farrah's -- umm, footsteps ... with a backdoor scene.

We're told she's seriously considering it ... so get your credit cards ready.

Farrah Abraham has to get something off her chest about Mackenzie McKee’s C-cup campaign -- buy your own boobs!

Our photog spotted Farrah sipping cocktails at the Mondrian Hotel in LA and asked about her fellow "Teen Mom" alum's breast implant fundraiser. McKee's asking for contributions toward her $5k boob job on MyFreeImplants.com. Last we looked she raised around $25.

Farrah threw some serious shade on Mackenzie, saying she's a mooch.

WWE junkies can rejoice, because WWE Diva Sunny may get in the ring for a XXX face plant, because we've learned she's inclined to sign on with a huge porn company.

Sunny tells TMZ she's been mulling over Vivid honcho Steve Hirsch's 6-figure porn offer and is now 60/40 in favor of it.

But there's a snag. Hirsch really wants the scene set in a wrestling ring, but Sunny thinks the gag has been played out.

Sunny favors the more traditional setting, like a hotel room.

The 42-year-old won't get flak from her boyfriend. She says her 27-year-old man is excited and wants an advance screening.
