Delta Goodrem's 'gross' spitting game with ex Brian McFadden

He’s the controversial shock jock who shares pretty much everything with his KIIS FM listeners.

And Kyle Sandilands did it again this morning, when he spilled all the gossip about his former friend, Brian McFadden’s relationship with Delta Goodrem.

“I remember when I’d have them around my house and they were in love and sometimes would spit in each other’s mouth,” Sandilands said on his show.

His co-host Jackie O seemed shocked and asked Kyle why they would do something like that?

“Fun, they said fun,” he replied.

“But I always thought, ‘Wow! That’s weird.’

Kyle went on to explain that Delta ‘would sit with her mouth open and Brian would spit into her mouth and Delta would spit back into his mouth’.

Jackie O claimed it was ‘gross’ and said she would ‘throw up’ if someone ever spat in her mouth.

Irish singer Brian, started dating Delta in 2004, with the pair getting engaged in 2007.

However, they split in 2011 and are said to have signed an agreement claiming stating they will never publicly discuss the relationship.

In 2012, Delta did however tell Vogue that she was ‘really unhappy’ and that she ‘didn’t know how to get out’.

“I learnt. I got there in the end,” she said.

Former Westlife singer, Brian, used to be one of Kyle’s good friends and even attended his wedding to former pop singer Tamara Jaber in 2008.

However, the pair’s friendship came to an end in 2015 when Kyle pulled out of best man duties for Brian just before his wedding to Vogue Williams.

Brian has since split from Vogue and Delta is now rumoured to be dating rock singer Matthew Copley.
