The musician is rumoured to be dating Dornan’s co-star Dakota Johnson.
The 72-year-old actor ran into Martin at Ellen DeGeneres’ star-studded 60th birthday party and could not stop gushing about him when she appeared on the NBC talk show.
“I’m gonna talk about Chris Martin. He was with Dakota, right – they’re a couple. Got it? So, what I’m saying is – he’s gorgeous.
That face got better with time. He was wearing a hat like this – oh, it was to die for,” Keaton told the audience.
The Oscar-winning actor admitted she did not know who Martin was until that day.
“That’s the other problem – I didn’t know who he was. But, I saw him and I noticed that he was gorgeous,” she said.
When asked about Dornan, Keaton called the actor a “very nice looking man”.
“He’s kind of scary, too, because of what he does to the girl – the Dakota girl,” Keaton added, referencing his BDSM-inclined character, Christian Grey in the film.
