The gorgeous Hunger Games actor, 23, enjoyed a night out at the HUGO BOSS flagship store opening in New York on Tuesday evening (24 September).
Reps for Liam and Miley, who began dating after meeting on the set of 2009 romantic drama The Last Song, confirmed on 16 September that their engagement had ended.
Liam is now thought to be romancing Mexican actress Eiza Gonzalez, after the pair were caught kissing in Beverly Hills after his split from Miley became public news.
Last night, however, the Australian actor flew solo as he joined a group of male friends including new dad Josh Duhamel at the swanky clothing store.
He was taking a break from working on the next instalment in The Hunger Games franchise, Mockingjay, which has been filming in Atlanta. The second movie, Catching Fire, hits cinemas this November.
Liam's boys' night out came the same day that a rather famous singer admitted he wouldn't mind picking up where Miley left off...
During an appearance on The Ellen DeGeneres Show this week, Sir Elton John joked: "[Miley] is a terrific girl. I'll take her old boyfriend though. As the French say, 'A bit on the side'. He's gorgeous...those Australians."
