Has Matty J betrayed Laura with another girl?

Matty J publicly declared his love for Laura in the finale of The Bachelor last week.

But just days into their relationship, the loved up couple have been rocked with claims of a shocking betrayal.

According to New Idea magazine, Matty Johnson was on a date with Laura during filming of the show when tried to "flirt" and and line-up a meeting with Kiri Kennedy, a barista.

"A person from the production team approached me and said, 'Matty is with his girl right and can't talk right now, but he would like you to hang around and meet him after she leaves,'" the 21-year-old told the publication.

The waitress went on to say that she was horrified by his "appalling behaviour" and declined his offer, but feels for Laura given his actions.

"Laura was the winner which is outrageous really. It's hard to imagine she is 'The One'," Kiri said.

The claims follow reports in Woman's Day that Matty J struggled with his final decision, saying it was in "hell for days" prior to giving runner-up Elise the boot.
