SHE took a huge gamble when she forked out £80 buying someone's lost suitcase from Heathrow airport.
And Bex thought she'd hit the jackpot when she opened the luggage and spotted a Fendi T-shirt sitting right on the top.
But as the unpacking continued, she realised she might have been celebrating a bit too early.
"It cost me £80 in total, so hopefully it was worth it," she said in a video on her TikTok page.
"Weighed an absolute ton, so I thought I'd get the scales down to weigh it.
"Ended up being just under 10kg!
"Hopefully it's not a waste of money."
She admitted she was "super excited" to open the case, and quickly realised it was a man's luggage.
Bex then looked delighted as she pulled out a Fendi T-shirt, before deciding to put on some gloves as she delved deeper into the case.
"There's a load of stuff in it, but I definitely feel like we got bumped," she said.

Pulling out some sandals, Bex admitted: "I don't even think Jesus would wear these!
"I mean, oh, no!"
"And these ones as well," she added of some cream sliders.
"What even are they? They're the ones you get in Turkey for free!"
Of a striped T-shirt, she said: "This looks like something my dad would wear!
"Literally looking through, there's loads of unbranded stuff that I've never even heard of.
"This person, I think, did themselves a favour by losing this suitcase, because I certainly wouldn't claim it!"
However, the contents of the case haven't put her off buying another one, as Bex admitted she'd be interested to see "if anything actually was decent to turn up".
"It's cause the airport staff take out all the good stuff and sell the rest," one person commented on the video.
