KJ Apa seen 'packing on the PDA' with American actress Britt Robertson - reports

Kiwi actor KJ Apa is rumoured to be in a relationship with his A Dog's Purpose costar Britt Robertson after the pair were reportedly seen canoodling at a Comic-Con party.

According to gossip publication US Weekly, an unnamed source claims Riverdale star Apa was "hugging" Robertson and the two were "leaning in and kissing each other".

Apa and Robertson, who will reunite on the silver screen for the upcoming film I Still Believe, were reportedly attending an event put on by Entertainment Weekly.

Sources said the potential new couple were spotted hanging out with Apa's Riverdale costars Cole Sprouse, Lili Reinhart and Camila Mendes. 

The alleged kiss may well have been Apa and Robertson's first in public, but the two have already locked lips on screen as young lovers Ethan and Hannah in the 2017 film A Dog's Purpose.

Us Weekly points out the pair have also been active on each other's Instagram accounts since earlier this year.
