It’s been 16 years since the 55-year-old actor locked lips with the 74-year-old actress in Nancy Meyers’ rom-com, which amassed $266.7M at the box office and 72% on Rotten Tomatoes.

Diane received an Oscar nomination and scored a Golden Globe in 2004 for her role as successful playwright Erica Barry, who dates younger cardiologist Julian Mercer (Keanu).

Arm in arm: Keanu Reeves enjoyed a flirty reunion with his former Something’s Gotta Give onscreen leading lady Diane Keaton during the 92nd Academy Awards on Sunday

‘You know, it’s been a long time since you and I made that movie, that movie Something’s Gotta Give. Remember me in it?’ the Keaton Red winemaker asked onstage Hollywood’s Dolby Theatre.

After Reeves gushed ‘Yeah, you were amazing’ then Keaton (born Hall) replied: ‘You were amazing!’

The eccentric LA native smiled: ‘We had some really, well, let’s be frank – it was a good time!’

The Beirut-born Canadian replied: ‘It was amazing! Good times! You and Jack [Nicholson]…’

Throwback! It’s been 16 years since the 55-year-old actor locked lips with the 74-year-old actress in Nancy Meyers’ rom-com

Didn’t end up together: Diane received an Oscar nomination and scored a Golden Globe in 2004 for her role as successful playwright Erica Barry, who dates Dr. Julian Mercer (Keanu)

That’s when Diane scoffed: ‘I wouldn’t go that far.’

The coy pair then presented the best original screenplay trophy to Parasite filmmaker Bong Joon-ho, who also won best foreign film and best director.

Keaton showcased her kooky sense of style in a Ralph Lauren Collection ensemble which mixed both plaid and gingham patterns.

The Oscar winner doesn’t believe in women wearing gowns ‘after age 60’ and she will never get plastic surgery.
