Armpit hair is so fetch to Rachel McAdams.
The 44-year-old “Mean Girls” star showed off her unshaven underarms in a photoshoot with Bustle published Tuesday.
The web women’s magazine reported the actress and mother of two requested her images be edited as little as possible.
“With this shoot, I’m wearing latex underwear. But I’ve had two children. That is my body, and I believe that’s so necessary to reflect back out to the world,” she said within the accompanying interview.
“It’s OK to look your best and work at it and be healthy, but that’s different for everybody.”
In a single image, the actress’ long armpit hair could be spied as she lays on a red couch.
It may be seen again in one other photo that shows her standing with one hand behind her back while wearing a slinky white dress.
McAdams, who’s promoting the film adaptation of Judy Blume’s “Are You There God? It’s Me, Margaret,” shares a 5-year-old son and a 2-year-old daughter together with her longtime partner, screenwriter Jamie Linden, 42.
The couple keep it hush on their private lives, but McAdams joked to Bustle that she “felt like a milk machine” while pumping and breastfeeding between scenes of the movie.
In a video posted to Bustle’s YouTube channel, McAdams gives her preteen self advice on growing up — including the choice to begin shaving her legs.
“Well, I’m going to offer you the recommendation my — your mother — gave me,” she began.
“‘Once you begin, you’ll be able to never stop,’ and I remember rolling my eyes about that, and considering, ‘Ugh, that’s not the fun answer,’ nevertheless it’s so true.”
“Life is long once, shaving is intense, but for those who’re gonna go ahead with it anyway, watch the ankle bones, the shins,” McAdams advised.
“You’re gonna go to Bible camp and think it’s okay to shave without shaving cream, and it’s gonna be terrible,” she continued, seemingly drawing upon her own experience.
“At all times have shaving cream, after which for those who wish to stop shaving again someday, that’s okay, too,” McAdams concluded.
The Post has contacted McAdams for comment.
Her armpit hair caused quite a stir on social media.
“Dear Lord…she has more pit hair than me. Unsure who exactly really wants pit hair. It’s kinda worthless,” one hater wrote on Twitter.
“That’s just nasty,” one other claimed.
One even nicknamed “The Notebook” star “Rachel McArmpitts.”
One other asked: “Am I seeing badly or does she have armpit hair?”
Meanwhile, on Bustle’s Instagram, fans praised McAdams for keeping the photoshoot real.
“Love her for embracing her natural beauty!!!” one applauded.
“Considered one of the few celebs in hollywood who embraces her natural beauty and haven’t done any plastic surgeries. a lot respect for her,” one other raved.
Another person celebrated: “That is what I needed to see after I was growing up! Yes.”
