Married At First Sight's Booka Nile has spilled the beans on her time in bed with her 'groom' on the show.

The 31-year-old musician got very candid about Brett Helling during an Instagram Stories Q&A with fans on Monday night.

'Was Brett good in bed,' asked one fan, to which an impressed Booka answered, 'Such a bold question!'   

'Um, he was okay,' said the reality TV star.

However, she then went on to admit that the electrician, with whom she was paired on MAFS, 'was blessed though, if you get my drift. Like, size wise.'  

The salacious reveal comes after Nile unveiled a dramatic hair transformation on her Instagram Story last month.

The Perth-based beauty visited her favourite salon to get a fringe cut, following a recent poll among her fans. 

She shared a selfie from the salon chair ahead of the chop, writing: 'Blaming all of you who voted yes to this happening when I regret this decision'. 

The reality TV star then shared a video of her stylist brushing out the top section of her tresses to create a fringe.

She followed that with a clip of herself looking shocked as the hairdresser finally did the cut, with the caption: 'No going back now.' 

At the end of her appointment, Booka proudly showed off her new 'do as she twirled around in the salon chair.  

Booka rose to fame on season eight of Married At First Sight and was partnered with electrician and psychology student Brett Helling.

But they split before the final vows. 

Brett later said the pair had 'tunnel vision' while on the show, and they realised their relationship wouldn't last in the outside world.
