After going head-to-head with Spencer Matthews when it came to his former flame Emma Walsh, Ollie moved on from his heartbreak by confiding in Tiff and taking her out for a dinner.
Speaking to Reveal recently, Ollie kept coy when it came to his situation with Tiff, but he did admit he didn't expect feelings to surface between the pair.
"I can't say too much, but I wasn't expecting it," Ollie exclusively told us.
"We'd both gone through break ups and we both wanted someone to text in the morning and night, you know to report back to someone as you do," he added. "We've got this friendship, relationship... flirty thing."
Gushing about his co-star, he said: "[Tiffany's] wonderful. Heaven. Lovely."
Following her split with Sam Thompson, Tiffany confessed to her older sister Lucy Watson that she had been enjoying texting Ollie.
When Lucy tried to put her off her new love interest, Tiffany stood her ground and said she wanted to continue speaking to Ollie, with the reality star later agreeing to a date.
However, her ex-boyfriend Sam revealed they had hooked up after their break up and was vowing to win Tiffany back, giving Ollie a bit of competition.
Things then got more awkward when Sam actually bumped into Ollie as he was buying flowers for Tiffany ahead of their date.
Viewers later watched as Sam apologised to Tiffany for everything that had happened between them. While Tiffany had admitted to cheating on Sam, he told her he couldn't see past her kissing someone else and was later accused of cheating too.
Sam told Tiff her missed her and wanted them to work things out, however, she had other ideas, telling her former flame it was "too late".
However, Sam and Tiff have sparked speculation they have now rekindled their romance. Reveal reported earlier this month that the ex-couple were spotted on a "date night" with Binky Felstead and her boyfriend Josh 'JP' Patterson.
Ollie, meanwhile, seemed to confirm there was unfinished business between Tiff and Sam, after revealing nothing more had happened with himself and his co-star.
He told BANG Showbiz: "There is nothing going on really now sadly. I think there was a spark... But I'm not going to stand in the way of her and Sam. There are too many emotions there and I don't want to be the person in the middle frankly."
