Kendall Jenner recently turned 18 and she may have got the oddest birthday surprise ever.

The reality star was celebrating her 18th birthday on Sunday (Nov 3rd) and she has already received offers from the most lucrative porn companies to star in one of their films.

According to TMZ, at least six companies are showing interest in hiring Jenner for a starring role in front of the camera.

The report also states the site, Bangyoulater.com, claimed it is willing to pay the 'Keeping Up With The Kardashians' star $1.8 million and let her pick any partner she wishes to perform with.

Kendell may follow in the footsteps of her older step sister, Kim Kardashian, after a sex-tape of herself and R&B singer Ray J emerged in 2007, which helped the 33 year-olds rise to fame.

No doubt it came with a burden of shame and embarrassed as well.

The 18 year-old is an aspiring model as she often speaks of her desire to become a 'Victoria's Secret' beaut, but a career in porn is unlikely due to her being branded as the "shy" member of the large family.

Other porn companies taking an interest into the brunette beauty is 'Brazzers', 'Babes' and 'Digital Playground', who allegedly offered Kendell to work on screen with porn star Jesse Jay.

Jenner posted a photo on twitter of her starting the birthday celebrations with Krispy Kreme doughnuts for breakfast, and before long the rest of the Kardashian clang sent their best wishes via social media sites.

Kim took to instagram to wish Kendall all the best, "Happy 18th Birthday to the sweetest girl I know @kendalljenner I hope your adult years are filled with happiness & so much love," she wrote.

Would Kendall's "adult years" begin with a career move into the X-Rated film industry?...highly doubtful.
