The actors were seen sharing sweet kisses at the Cannes Film Festival for the premiere of their movie, "The Dead Don't Die," on Tuesday.
Murray, who's 42-years Gomez's senior, was photographed planting one on the side of her cheek while she posed for photographers.
She proceeded to reciprocate the love by showing off her playful side with her co-star.
Wearing all white and pairing the look with red lips, Gomez seemed happy and healthy on the red carpet, months after seeking treatment for depression and anxiety.
*Spoiler* Gomez loses her head in the Zombie movie.
The film, which also features Chloe Sevigny, Adam Driver and Austin Butler, comes out on June 14.
