The 42-year-old fashion favourite has had the top of her ear pierced, alongside her make-up artist friend Gucci Westman.
Gucci shared a photo on her Twitter page showing the two ladies posing with their new piercings.
"Me and #jenniferaniston got our ears pierced today!! #memories @mrschrismcmillan # loveyou," she wrote next to the snapshot.
Gucci and Jen are great friends, and the mum-of-two has previously described the actress as "one of my favourite girls in the world."
The makeup guru has a stellar client list that includes Cameron Diaz, Gwyneth Paltrow, Drew Barrymore and Natalie Portman.
Jennifer revealed this week that she has had six inches taken off her hair after it was damaged by a Brazilian blow-dry treatment.
"It wasn't for a role… I did this thing called a Brazilian and my hair did not react really well to it," she told ELLEUK of the treatment, which uses formaldehyde and keratin to keep locks straight for up the three months.
She later told Vogue that her decision to go for the chop was spur-of-the-moment.
"I was flipping through the television channels and I paused it to take a picture and I sent it to Chris [McMillan, her hair stylist], and he said, 'That's Lawren Howell from Vogue!' And then he said, 'I just cut that!' So that's it."
