They ended their relationship (and broke our hearts) in 2013, even though they were set to wed.
But now the pair are sparking reconciliation rumours as The Daily Telegraph has reported that Liam and Miley were spotted together at the Falls Festival in Australia's Byron Bay.
The singer and actor were reportedly seen "cuddling and kissing" at the music festival, as they joined Liam's two brothers.
The Hunger Games star shared snaps of his time with his two hot bros, but Miley has yet to be captured in a snap.
The DT also reported the ex's arrived at the festival late and were seen walking backstage to the VIP area with Liam's brothers Chris and Luke and their wives.
We just hope they're back together for real this time!
