The selfie saw the 21-year-old stood in front of a mirror, with what appeared to be a rolled-up bank note, a credit card and a white powder in front of her.
Amber then took to Twitter to issue a statement on the matter, writing: "I was completely naive to what was lying on the table in front of me.
"I don’t know for sure what it was, but I do know what it looks like, and I am devastated. I have never and would never take drugs, or knowingly be around people who do. That is not who I am."
But Love Island alumna Jessica Shears has issued a warning that former dancer needed to "smarten up" now she's in the public eye.
Speaking exclusively to Daily Star Online at the In the Style Totes Over It Valentine's Day bash, 24-year-old Jess explained: "I wouldn't have said it was the smartest move, but everyone makes mistakes and I get that, but there's a lesson to be learned and its to be more vigilant.
"You need to smarten up. You've got to be smart, especially when you're in the public eye."
Jess, who is now loved-up and currently planning her wedding to her very own Love Island beau Dom Levers, said she has cut back on the wild nights since being engaged.
She added: "All we do is sit at home with our dogs! There's nothing suspicious about what we do.
"We're really open and we're really straight-laced. So for me a wild night is a bottle of wine."
Fiancè Dom added: "I'm 27 so I feel like I'm nearly over the hill [compared to the other Love Island stars]. These are enjoying it and I feel like I've done that now.
"Honestly, it's one of those things - if you're in that situation, I don't care who you are, you know what everyone around you is doing.
"Personally, I wouldn't put myself in that situation. And I wouldn't want anyone taking pictures and I wouldn't let anyone take a picture of myself.
"It's just being smart with what you do and who you hang around with. It's her mistake and I do feel bad for her as it's come down on her like a tonne of bricks."
Jess also defended fellow Love Island cast member Olivia Attwood, with her pal in the villa being blasted by critics for "faking" get relationship with Chris Hughes.
"Olivia is far too honest to be fake about anything," she explained. "If she thinks something, she'll say it. I don't know how people can call her fake."
Jess recently opened up about her upcoming Mykonos nuptials to fiance Dom, revealing while she is yet to say yes to the dress, preparations for the ceremony are slowly coming together, and the pair are desperate to start a family.
In a candid new interview with Closer Magazine, the busty model said the couple are looking forward to their intimate ceremony in Greece.
She said: 'I'm so excited. I've never wanted a big wedding as my friendship group is tight-knit and I've only got a small family, we've only got around 30 or 35 guests which is perfect.
'I've tried on a few dresses but I need to start looking properly. It's slowly all coming together.
And the hot couple, who announced their engagement in September after three months of dating, are keen to start a family in the not too distant future.
Jess said: 'I'm so broody. Dom and I are both desperate for a baby, we'd like three kids in total. Hopefully when the time is right, it's something that will happen.'
