A dad and his daughter have taken their loving relationship to the extreme to win money – by making out live on a radio show.

The pair went on The Kyle and Jackie O Show on KIIS radio in Sydney, Australia to win $1,000 (£548) in the game "Boyfriend or Daddy".

As suggested by the name, the hosts have to guess if the female contestant, Stacy, brought her dad or partner along judging by the kiss.

They can walk away with a cash prize if the hosts guess it wrong.

In footage shared on the show's Instagram account, host Jackie says: "This is your boyfriend or your dad? So feel free to kiss as much as you want."

Stacy doesn't need to be asked twice and goes in for a passionate kiss with her 46-year-old dad Nick.

Presenter Kyle Sandilands is shocked and says: "Oh they are kissing! It was a full make out. It has to be a boyfriend."

Kyle and Jackie are convinced that they are in a relationship, with Kyle adding: "It can't be the father, no one kisses their father like that... unless you live in the mountains and have no neighbours."

Eagle-eyed viewers even spotted Nick touching Stacy's leg after the snog and branded them a "disgusting" pair.

Stacy then reveals the truth, saying: "The things we do for money...this is actually my father!"

Jackie is stunned and asks people listening to the show if they would kiss their dad for $1,000.

Kyle jokingly replies: "Then I will have to dig him up from the grave."

One viewer took to social media and answered: "OMG, no, not even for a million!!"

Many commented with vomiting and angry emojis.

Another wrote: "This is so, so wrong on so many levels."

"Nope no amount of money is worth tarnishing the pure innocent love between father and daughter in my eyes," a third added. "This can never be undone."
