Octomom -- Check Out My PORN STAR Pose

HOLY MAKEOVERS!! Porn is doing wonders for Octomom -- 'cause the mother of 14 is fully glammed up in this photo from the set of her self pleasure video.

The gold and black bikini snapshot of Octo, aka Nadya Suleman, was leaked by another porn star ... Jessica Drake, who "coached" Octo through her performance.

The porn studio behind the video -- Wicked Pictures -- just issued a press release, in which Nadya says, Drake "opened up my eyes to a whole world of self-pleasure that I could never have imagined." Drake says, "I am honored to have helped [Octo] explore her sexuality."

According to the release, the video will show Octomom in a "variety of erotic scenarios" focused on solo masturbation -- all poking fun at her public persona.

Octomom calls the experience "the best, most powerful, and most liberating thing I've ever done."

Compare the above pic to Octo's topless spread earlier this year, and it's easy to see the improvements in her appearance.

Let's hope her finances get a makeover too.
