AN OBSESSED fan has posted a rather raunchy love song about MasterChef guest mentor Shannon Bennett online.

29-year-old singer and violinist Jane Patterson told news.com.au that she wrote the song because the chef had “drawn her in” during the current series of the hit Channel 10 show.

“I couldn’t sleep one night and the song just came to me and I finished it the next morning,” said Patterson.

Posted online a week ago, the song features such tongue-in-cheek lines as:

I know your magic would unlock

All the mysteries inside my mystery box

And your exceptional knife skills

Have a way of heating up my grill

And what I’d do with your crème fraîche

Is smear it all over my flesh

Patterson, who has penned several parody songs for her cabaret group Ginger and Tonic, says she’s aware that Bennett has heard the song.

“Matt Preston tweeted me and said he’d played it for Shannon and he blushed,” she said.

“But I’d love to hear from Shannon himself, that would be the cherry on top.”

Oh, and in case you’re wondering, Patterson’s well aware that the chef is happily married to former Neighbours star Madeleine West.

“I’ll just have to love him from afar,” she said laughing.

Have a listen to the surprisingly catchy song:
