Billy Crudup and Naomi Watts support each other's "agenda"

He told People magazine: "We've been doing this for a long time.

"I think we have some idea of how each of us manages our careers, and so we do the best that we can to just be supportive of the other person's agenda."

The couple, who are both 57, previously admitted it is "much easier" to attend Hollywood events together.

Speaking at the 2024 Primetime Emmy Awards, Billy told E! News: "We were talking about it this morning, what a power couple we were. It's incredibly gratifying to be by her side."

Naomi added: "It's much easier to do this with someone. Having someone on your team, holding the hand, little bit of eye contact just to centre yourself."

And the Morning Show actor - who has William, 21, with Mary-Louise Parker -told how they are happy to help each other prepare for work.

He said: "We talk about work quite a bit and we'll run through ideas that we'll have for scenes or characters. And I have to say that there are no competitive vibes at all.

"The acting we love talking about, and we support each other's work... Don't ever play Scrabble with her!"

Naomi - who has Sasha, 17, and Kai, 16, with former partner Liev Schreiber - previously admitted falling for Billy in 2017 took her by surprise because she had started work on Gypsy in "no mood for romance or flirting.

She wrote in her book Dare I Say It: Everything I Wish I'd Known about Menopause: "I didn't know for the longest time that my co-star on a TV show was going to be the person I belonged with.

"There were no signals going off. I was in no mood for romance or flirting. I planned to hold myself together for my kids and keep my head down at work.

"Like so many women my age, I found my libido wasn't what it had been in my 20s. Maybe one day I'd find love again, but I knew I wouldn't be looking for it for the foreseeable future - and certainly not at work...

"Billy and I chatted on set during lighting changes and I'd have said we were friendly. But for a very long time, that was as far as it went.

"I was so closed off to love that in the months and months of shooting, even after we'd simulated sex on screen many times, dry-humping each other to the point of exhaustion, I hadn't given romance with him a thought.

"Then one day during a sex scene, he spontaneously flung a pillow across the room while ravishing me with such passion that I blushed and broke character. 'Oh! Why, hello, sailor,' I thought to myself, and as me, not as the woman I was playing. Then, 'Wait, that felt like... something.' "
