OLIVIA Bowen was slammed by fans for promoting an 'unreliable' birth control app.
The former Love Island star teamed up with a brand that monitors fertility levels in users.
She said that she was a proud advocate for "non-hormonal" contraceptives and wanted to "spread the word" on the "side-effect-free" birth control app.
Holding her phone to the camera as she flashed a smile, she wrote: "As you guys know, I am all for choosing a non-hormonal, non-invasive birth control method.
"First of all, we’re all different, what’s right for me may not be right for you. But personally, using [the app] has helped me gain a much better understanding of my body.
"The app supports women throughout different phases of their fertility journey and can be used either as birth control to prevent pregnancy or as a useful tool when trying to conceive."

While many fans were complimentary of the app, some were skeptical.
Many argued that it was a good app for monitoring monthly cycles, but that it shouldn't be used as a preventative tool against pregnancy.
"I am now pregnant," one wrote with a laughing-crying face.
"Please don't do this promotion! It's not reliable!" said a second.

What are fertility apps?
Fertility apps track the user's periods to predict the time that the woman is most fertile.
They are used by couples who are trying for a baby, as well as for women who want to avoid pregnancy.
The apps have also become popular for women who do not want to take hormone-altering contraceptives, such as the pill.
Some couples choose to have unprotected sex during low fertility windows as the chances of falling pregnant are much lower.
This always comes with the risk of unplanned pregnancy as pregnancy can occur at any point in a woman's cycle
"Last time I saw someone promote this they announced their pregnancy not long afterwards," another added.
"I used to love your context but it's just AD AD AD! Your going to lose so many followers (sic)," a fourth chimed.
However, many fans have sung the app's praises, with one writing: "I have used this for a year (with oura), think it’s great".
"I used this to help me track ovulation to help me get pregnant! My sister uses it to not get pregnant. It’s a great app," another said.
"Love it!! I’ve been using it for a year," echoed a third.
The 30-year-old rose to fame after finishing as a runner-up on the second series of Love Island, with her now-husband Alex, back in 2016.
Olivia and Alex recently sold their £1.3 million Essex dream home to trade it for a luxurious mansion.
The star talked to The Sun about her new home and what she's most looking forward to.
Olivia said: "We've designed a little kitchen barbecue area, getting a pizza oven, and we'll have seating. So the love island is still creeping in."
"I've become a lot more confident in my style and my design process, and I think that that's just helped with this house.
"It will show because my style is very different to the old one. It will look very different and I think people are not going to expect what it's going to look like."
She added: "The last house was very modern, a lot of like clean lines. A lot of sort of beige, minimalist kind of thing, but this house is very different.

"There's a lot of colour, a lot of pattern. It's just very country. We have a lot of beams and things, so yeah, it's kind of completely different."
The former reality star got into interior design in a big way after her time on the show, and has kept fans updated on her house renovations through an Instagram account dedicated to the topic.
