It was Jack and Dani who won love Island 2018 last week with over 80% of the vote.
Olivia appeared on the show last year, making it to the final with then boyfriend Chris Hughes.
The pair split up earlier this year following their very own reality show on ITV2.
Now Olivia has issued Dani and Jack a warning after reports that they too were set for their own spin-off series.
Olivia said this week: “We all knew Jack and Dani were going to be the winners, didn’t we? They’re very sweet and I do feel like they were the most solid couple, so of course they deserved to win."
Writing in her new! magazine column, Olivia continued: "There are rumours abut them landing their own show, just like Chris and I did. My advice would be to really think about it and don’t jump into it too soon, because it adds a lot of pressure.
“Then again, my relationship with Chris was s**t, so it probably would have f**ked up further down the line anyway. If Jack and Dani are really solid, which they do seem to be, then go for it!”
Applications are now open for Love Island in 2019.
After the success of this year's run - which had over 4 million viewers in the final - another series was always going to happen.

"Once again our Islanders will take up residence in a spectacular luxury villa in the hope of finding love. But to stay on the island, they need to couple up – and more importantly – win the hearts of the public."
In order to apply, you need to be at least 18, have valid travel documents and be free to enjoy a long hot summer next year.
