Liam sparked rumours of a romance with Gabriella after introducing the brunette beauty to his parents Craig and Leonie in Byron Bay last Friday.

The 21-year-old stunner appeared to hit it off with the 29-year-old actor’s mother and father as the group got to know each other over a family lunch.

In October, Liam was linked to actress Maddison Brown, 22, after they enjoyed a date in New York, but it appears nothing progressed between the pair.

The Byron meet-and-greet comes as he reportedly prepares to lodge paperwork for his divorce with his estranged wife Miley Cyrus.

Liam returned to Australia last week after wrapping filming on his latest project, TV show Dodge and Miles, in Toronto, Canada.

It is believed he will now remain Down Under for Christmas with his famous family.
