“I can honestly say Jen is the best in so many ways and one of the most rocksteady humans I’ve ever met,” he said.
“I’ve only seen her angry maybe, like, two and a half times in the 40 years I’ve hung out with her. Jennifer is beautiful, everyone knows that. She makes us smile and laugh. And she has a warmth to her that is intoxicating. She is everyone’s best friend.”
Aniston walked the red carpet alone at the event but posed for photos inside with Curtis.
When the Morning Show star took to the stage to accept her award, she called out the dangers of AI on the entertainment industry.
She said: “That’s what keeps me showing up every day, it’s the friendships and the shared belief that storytelling still matters that baring our souls as actors and creators still matters, something that AI will never be able to duplicate no matter how smart it gets.”
Aniston recently praised Curtis, 50, as “very special” and “very normal”.
She told Elle magazine: “Hypnotism is one of the many things that he does. He’s quite extraordinary and helps many, many people.
“He’s very special, very normal and very kind, and wants to help people heal, move through their trauma and stagnation into clarity. It’s a beautiful thing to commit your life to.”
The couple first sparked romance rumours when they were pictured on holiday together in Mallorca, Spain, over the Fourth of July weekend this year.
After Aniston recently made their relationship Instagram official, Curtis reciprocated by adding more pictures of the pair together and alongside the snaps posted on Instagram, he wrote: “If this is a dream, I don’t want to wake up.”
