LaPaglia, 58 and Henkel, 28, started dating in 2015, just months after the actor split up with his wife of 17 years, Gia Carides.
Henkel, who is 30 years LaPaglia's junior, debuted her diamond ring on the red carpet with her fiancè last night at Yves Saint Laurent beauty party, YSL Beauty Club Takes Over Melbourne.
Congratulations to the pair!
