On Monday, Lavigne, 38, and Tyga, 33, were photographed sharing a kiss outside the Mugler X Hunter Schafer party at Paris Fashion Week.
The Canadian and American singers sparked dating rumors earlier this year, and have been hanging out a lot both in Los Angeles and Paris, the same city where her ex, Mod Son, proposed.
They certainly looked like a couple at the party, holding hands as they walked into the swanky bash.
Avril called off the engagement to Mod in February, about a year after he popped the question.
It was alleged that the former couple had been on and off for several months before she pulled the plug.
The couple were previously seen arriving together at Leonardo DiCaprio‘s party at Kùkù restaurant in Paris last Wednesday.
