An Instagram star accidentally live streamed the moment she got steamy with her boyfriend to thousands.

18-year-old vlogger Kristen Hancher, from Los Angeles, was getting having a moment with her partner, Andrew Gregory, but didn't realise she'd started recording - for three whole minutes.

It was shared live on her Instagram story and seen by 14,000 of her 3.9 million followers.

Luckily for her, the phone was face down, but it picked up the audio of what was going on.

Kristen immediately took the post down after realising her huge gaffe.

She told her followers: "Whoever saw my live, I just wanna apologise; that was totally NOT intentional. Delete it from your mind."

"That was super embarrassing and super uncomfortable."

"But for real, guys, s*** happens. Accidents happen. You have to move and and pretend like it never happened and go on with your life. That's what I'm gonna do."

Kristen added: "I apologise to all my fan pages. I know you all have been upset because I never gave you guys a full explanation. On what happened on my live."

"On my Instastory. I accidentally went live and found out three minutes later and 14,000 people were watching. I am so sorry."
