Trinny Woodall's partner Charles Saatchi unwittingly appears on her live stream naked

Trinny Woodall's partner Charles Saatchi has made an unwitting and revealing cameo during one of her livestreams.

While the fashion and beauty guru was giving tips to her followers, Saatchi was spotted in the frame as he headed towards the bathroom.

It seems Woodall did not notice the art collector’s sudden appearance, as she continued to speak to her fans on Facebook Live.

However, the star had covered her own face with a £400 LED mask, which may have spared any blushes.

According to The Sun, a fan who had spotted Saatchi on the video commented: “I’m unsure if she knew he was in camera shot but after he walked past she put her hand up to hide that side of the bathroom.

“She had her mask on so I didn’t see if she was embarrassed or not.”

The video has since been deleted from social media.

Woodall started seeing Saatchi in 2013.

She regularly uses Facebook to interact with her fans, detailing her fashion, beauty and fitness regimes.

Having made a name for herself on BBC’s What Not To Wear alongside Susannah Constantine in the early 2000s, Woodall has since said she prefers using social media to broadcast.

“I think social media is the most exciting thing,” she told the Sunday Post. “I’ve never done photographs on social, it’s always been about having an immediate connection with video, and that’s the joy of social compared to, say, a TV show. Nobody is telling me what to do or editing me, so I feel like I can really blossom as myself.

“Online, we can make our own TV. We don’t have to have somebody else ‘cut’ us.”
