On Jan. 2, Gabriella and Liam's mutual friend, Silvia Serra, shared a series of photos from a New Year's Eve celebration in Bryon Bay. The sixth and seventh photos feature Gabriella in a couple of group shots, while the ninth photo in the series includes Chris Hemsworth creeping in the back of a group photo. Chris' wife, Elsa Pataky, is also featured in several photos. Though Liam isn't pictured at all, we can't help but suspect that he was also present for the festivities. Five days later, Gabriella shared two pictures on her own page of just her and Silvia from the party. Oh, and did we mention that Silvia is the wife of Elsa's half-brother, Cristian Prieto Medianu? Whether Liam was at the party or not, it's clear that Gabriella has been accepted into the Hemsworth network.
