The Hunger Games actor had been linked with Australian actor Maddison Brown, 22, after they were spotted on a date in New York in October, but it is believed that short-lived romance may have fizzled out.
Liam is also going through a messy divorce from his wife, Miley Cyrus. She is now dating Australian singer Cody Simpson.
Liam returned to Australia last week after wrapping filming on his latest project, Dodge and Miles, in Toronto, Canada. It is believed he will spent the holidays Down Under.
In October, Gabriella split from the 1975 singer Matt Healy after four years together, after a source revealed that his partying was coming between them.
Meanwhile, Miley and Liam's divorce is turning nasty. The exes, who were married in December 2018, are now moving through the divorce process, which could see them reunite at a status conference at the Stanley Mosk courthouse, California, on January 21.
"It's sure to get interesting," a source told US publication Life & Style.
"Miley and Liam haven't really spoken since they called it quits and the tension has been brewing."
Adding that Liam “still holds a grudge” against Miley for “flaunting her fling” with Kaitlynn Carter before the split was even announced.
