Oh dear… in the week since Kylie Jenner turned 18, she's been inundated with offers – some of which have come from less mainstream business operations.

Indeed, it seems that the teenage reality TV star is being courted by numerous adult entertainment corporations.

And they're coughing up seven-figure offers… if she agrees to do porn. 

Apparently Vivid Entertainment has already offered her an astonishing €9m to do a video with her boyfriend, Tyga. 

TMZ has learned that the company's head honcho Steve Hirsch has written to Kylie explaining: "Kim's sex tape helped launch her career and would be nothing but positive for you."

Meanwhile, BangYouLater is offering her €1.6m, saying: "This event will make you even more famous than either Kim K or Paris Hilton."  

They do specify, however, that her "scene must be at least 22 minutes in length".

Digital Playground, which claims to produce the world's biggest porn movies, is asking Ms Jenner to become its front woman.

The company writes, "Now that you are of legal age, we would like to offer you the opportunity to be Digital Playground's Brand Ambassador!"  

And they'd also like her to do porn: "We know you'll be great at this and with your banging body to match, maybe you'll be interested in becoming an adult star yourself!

"Join DigitalPlayground.com and be welcomed into a new, hornier family."

We're going to assume she's politely turning down the offers.
