Farrah Abraham is putting her porno money to good use. She previously said her daughter Sophia's college fund is paid for, and so are her own implants (breast and chin) and rhinoplasty, so now she can blow cash on fun stuff -- like Lamborghinis.

And she can also blow hot air about being a better role model than Kim Kardashian. Because there's no better person to look up to than someone who brings her daughter to negotiate a price for her sex tape.

In an interview with 'Entertainment Tonight,' the 'Teen Mom' turned 'Back Door Teen Mom' starlet says she and Kardashian aren't that similar, because, well, she's better than Kim.

“I don’t agree with everything that she’s done in her life, so I hope to live my life a little bit differently,” Abraham said, inexplicably adding, “I only want to be a positive influence and show positive things.”

Abraham also wanted to show the positive side of having a sugar daddy, but was denied. SeekingArrangement.com, a site that sets pretty girls up with rich dudes who pay for ... the pleasure of their company, said she approached them about an endorsement deal, but they rejected her.

“We could tell that Farrah wasn’t coming to us for the right reasons. She was just looking for a quick payoff, not a lasting mutually beneficial arrangement,” Brandon Wade of SeekingArrangement told Radar Online.

“There was a Sugar Daddy party in LA and Farrah wanted to come and then she told us she wanted us to pay her to join our website,” the site’s rep, Jennifer Gwynn, added. “She wanted to say that she wanted to find a sugar daddy and to have us pay her, but she didn't really want to find one. Farrah wanted money for nothing so we turned her down."

"Our website creates partnerships and Farrah is not someone who is actually going to benefit us,” Gwynn said, before running off to grab some aloe for the burn.

Abraham reportedly reached out to the site again just before 'Back Door Teen Mom' dropped, but they still weren't interested. And Mr. Wade had more to say about it.

"It saddens me to think that Farrah believed her actions would lead to a path of empowerment and self esteem. I think she will look back on this experience one day, and regret it," he mused. "She had this incredible opportunity to be a role model; the front door was wide open.

“But instead she chose the ‘back door’ to financial security, and she will soon come to realize that a lot of doors will be closed to her now because of it.”

We'd laugh at his play on words, but we're not so sure taking money from old dudes in exchange for, uh, "company" is that much more respectable than porn.

But what does Abraham care? She has a Murcielago now.

She signed another endorsement deal, this time with The Biggest Limo, who gifted her with "use" of the $400,000 lipstick-red whip while she's in LA -- letting her ride dirty for, well, ridin' dirty.
