Stu Laundy found out Sophie Monk dumped him on Instagram

Stu Laundy found out he was dumped by Sophie Monk at the same time as the rest of Australians ... when he read it about it on her Instagram.

The millionaire publican and father-of-four, 45, decided to do a bit of a publicity tour on Monday morning appearing on KIIS 1065's Kyle and Jackie O Show and Nova'sFitzy and Wippato speak about their split after meeting on Channel 10's The Bachelorette last year.

In both interviews, Laundy threw some not-so-subtle shade at the former Bardot singer, 38, when he explained how their relationship came to an abrupt end.

"It was Soph's [decision to split] and apart from being so publicly brushed, I have no hard feelings," he told Wippa Ryan "Fitzy" Fitzgerald and Michael "Wippa" Wipfli.

"I sort of found out via Instagram, but we both knew in our hearts it was pushing toward a friendship."

Kyle Sandilands, who is a close friend of Monk's, shed some more light on the break-up when he explained to his co-host Jackie "O" Henderson that Laundy could be aloof.

"I was talking to [Monk] before Christmas and I knew it was tough ... they weren't getting on that great," Sanidlands said.

He continued: "She was telling me, 'Look I like him, but he vanishes for a couple of days at a time.'

"I know what [guys] are doing when they vanish for a couple of days at a time ... getting away from you."

Laundy explained that he had been spending time with his children as they are his priority.

In what might have been the most awkward interview of the century, Sandilands then phoned Monk, who is currently on holidays in Canada, and put her on air with Laundy.

"At the end of the day, you make me laugh probably more than any girl ever and there's no way in the world I want to lose that," Laundy told her.

A usually mild-mannered Monk was less than impressed she had been duped by Sandilands in coming live on-air for free, saying she could have been paid quite handsomely for her side of the story.

She also said she would be open to ex sex.

Since the beginning of their relationship, Monk and Laundy had to constantly deny reports they had split and that their relationship was fake.

"I gave it the best shot I could and my intentions were everything I said I was looking for, but unfortunately it just didn't work out," Monk wrote on Instagram on Friday.

"As much as I respect him, we are just very different people ... There were no contracts or pressure to stay together whatsoever from anyone and we remain friends," she added.
