He burst onto our screens in Made In Chelsea in 2011, and along with his charismatic personality, everyone was in love with Ollie's trademark hair.
GIving us girls a good run for our money, Ollie's locks were long, glossy and super straight. Basically, he had dream hair!
His hair, paired with his love for anything with the Union Jack flag, made Ollie one of our favourite Chelsea boys.
Okay, so at first some may have gasped when Ollie decided to chop off his luscious locks in 2012 after having his ears pinned back. But, his radically shorter, slicked back hairdo was so Ollie, and we loved that look too.
Hair talk aside, it seems like it was just yesterday when Ollie confirmed he was leaving the show. It was actually back in August 2013 when he announced his exit, and we were gutted, to say the least.
But, you can imagine our reaction when we found out last month that Ollie was returning to the show that made his name. As any MIC fan would know, we were treated to a glimpse of Ollie's return at the end of Monday night's episode.
Ollie, who came in third place on Celebrity Big Brother in 2014, said of his return: "I am delighted to be returning to a show that I am so proud of being involved in from day one. I can't wait to be back on the Kings Road adding some more love, laughs and just a bit of the ridiculous!"
We're looking forward to seeing some cheeky fun from Ollie, oh, and lashings of fake tan!
