Aniston was on hand to give an award to her hairdresser, Chris McMillan, who gave her the famous Rachel cut.

As she presented him with the prestigious award, she said: “I am here tonight because I get to talk about my dearest friend, my brother from another mother, my husband that will never marry me because he’s gay, but maybe — there have been movies ’bout that — Chris McMillan.

“I just have a few things to say about you: You’re one of the most passionate and kind human beings that I’ve had the good fortune of getting to know and I get to call you my family.

“I feel blessed every day for that. We’re going on almost 25 years together, which is shocking to me.”

Discussing her famous haircut, she said: “If you’ve ever been within 10 feet of Chris, I’m sure he’s had his hands all over your hair, whether you want it or not. We love that about you. The amount of photo shoots, films, and commercials.

“Everyone, about 70-90 per cent — if not all of the crew — will leave with a McMillan haircut. It doesn’t matter if you wanted it or not.

“You leave, you feel beautiful, you feel sexy, you feel alive. Then you feel screwed, because nobody has the ability to actually do what Chris did to this haircut.

“I used to call it the Rachel hair, because I got that haircut, that was like, ‘Wow this is amazing,’ and then I was totally left with this frizzy mop on my head, because I had no idea how to do what he did. Nobody seems to know how to do what Chris does.”
