Ollie quit the E4 reality in August 2013, but some two years later, he is now returning to the show that made his name.
"I am delighted to be returning to a show that I am so proud of being involved in from day one," he said. "I can't wait to be back on the Kings Road adding some more love, laughs and just a bit of the ridiculous!"
Ollie was in Los Angeles this summer with some of the show's stars including close friend Binky Felstead, and at the time he was rumoured to be making an appearance in the spin-off show, although this was later denied.
However, it's now been confirmed that Ollie will be seen in the final episode of MIC: LA, as he welcomes Binky back to British soil.
Ollie, who took part in Celebrity Big Brother last year, was an original on MIC since it started in 2011.
As one of the show's most popular and memorable characters, Ollie was well known for his fake tan, eccentric dress sense and patriotic car.
When he quit in 2013, he said: "I've quit the show. I have done five seasons, I've had three breaks ups and I've come out as bisexual. The party's over for me."
We can't wait to see what happens next, as Ollie is sure to bring some drama and mischief when the new series of MIC returns.
