The reality star is fast becoming one of our biggest beauty icons thanks to her bold brows, cool inkings and ability to pull off more or less any shade of lippie, but she was forced to clear something up after posting a string of stunning new selfies on Tuesday (26 July).
Taking to the caption, Olivia mentioned that she used the Ofra Matte Liquid Lipstick in MINA, £16.99 to dress her smackers and even though she has dabbled with fillers in the past, she hit back at commenters who accused her of plumping up her lips a little more.
"Morning cutie pies! So my new found love is my OFRA Matte Liquid Lipstick! This one is in colour MINA," Olivia captioned her snap.
She continued, "P.S I haven't had fillers in 8 months and won't have them again, my lips are pouty. Go suck a fish if you hate it."
Of course, it wasn't long before Olivia's fans and followers shared their thoughts and many praised her for being honest.
"I like that you've told the truth! You had fillers, so what? You don't have them now and still look gorgeous, if not more so. Love you!," wrote one, while another said, "Haha the caption! Fillers or no fillers, still hot. Loving the lip colour too."
Talking to Reveal in this week's issue Olivia advised her fans and followers not to go under the needle, even though she had done once herself.
Olivia rather candidly said, "I would tell any girl to steer clear. A lot of girls get it done and don't need to – which is like me, my lips aren't even thin."
The star - loved up with island beau Alex Bowen - hinted that she really regrets going in for fillers and now finds it awkward and uncomfortable to look back at old photos of herself!
"Now I look at pictures and think I look weird!" she added.
With that in mind, Olivia isn't the only celeb to deny a filler refresh recently, as Ex On The Beach's Ashleigh Defty insisted that she hadn't opted for any more procedures, too.
"Pouting HARD!," Ash captioned a beautiful selfie posted to her Insta-account. "No I haven't had my lips done before people start their s**t," she hit back.
You tell em, girls.
