Zoella may be the Queen of YouTube, but even she's had the odd awkward moment online.
Unfortunately for the 25-year-old vlogger - real name Zoe Sugg - one of those awkward moments occurred yesterday.
It all started when Zoe shared a photo she'd taken of a man walking his dog on the beach with her Instagram followers. So far so innocent, right?
She'd captioned the image: 'I took this photo of a random man & his dog & other photos on the beach at sunset today! Click the link in my bio to give it a read. :).'
However, what Zoe failed to notice was that this man wasn't quite as random as he first appeared. In fact, he was Pink Floyd guitarist and vocalist Dave Gilmour. Ah.
She'd actually posted the snap almost two years ago, and since then her oversight had pretty much gone unnoticed.

But Dave's wife Polly Samson drew attention to the shot this week, when she Tweeted: 'Daughter's just drawn my attention to this "random man" on Zoella's feed.'
Of course, this led to a bit of an online frenzy. And unfortunately for Zoe, some music fans felt the need to write some pretty unpleasant messages about her.
One said: 'Generation YouTube is f*****,' while another commented: 'So stupid.'
But Polly had a different opinion, adding: 'To be fair #randomman had no idea who the #randomyoungthings were either. @Zoella LOVELY pic btw.'
Ohers have also lent their support, with one message reading: 'Everyone slating Zoella for not recognising David Gilmour when they couldn't pick a YouTuber out of a lineup.'
TBH, the YouTube generation isn't exactly Pink Floyd's target audience.
And while this all hilarious, it's also very sweet. We reckon Dave and Zoella should hook up for a proper photoshoot. Now THAT would break the internet.
