Bra tycoon Michelle Mone is a jack of all trades: successful businesswoman, international motivational speaker to would-be entrepreneurs, designer, and parliamentarian.

Let’s just hope she doesn’t add “recording artist” to her CV anytime soon.

The former Glasgow girl has posted a rather haunting video clip online of herself attempting to serenade her billionaire Scots boyfriend Doug Barrowman on karaoke.

Mone, 45, took singing superstar Whitney Houston’s 1986 smash hit Greatest Love of All - and completely murdered it - while a dubious-looking Barrowman, 52, looks on.

Though, whether he’s looking for a quick exit or gushing over his doting other-half is masked, thanks to the darkness, although he does applaud her as she leans in for a winch at the end.

Warning to readers before watching: you may find it difficult to get the sound out of your ears for many hours after.

Still, many of her loyal followers commended her on her performance. “Brilliant!!! Your very good!!” said one as another gushed: “Looks like your having the time of it. Loved your man gazing away at you there.”

Thankfully, though, she saw sense after the incident as she admitted: “I better stick to my day job. No #XFactor for me.”

She also threw in the hashtags ‬”#entrepreneur #businesswoman #business” too, although we’re not too sure what those ones have to do with her actions on the mic.
