Singer Miley Cyrus, who recently coloured her armpit hair in pink shade, shared a photograph of her Barbie doppelganger with pink hair in armpits.

The "We Can't Stop" songstress shared on photo-sharing website Instagram on Sunday, a photograph of her Barbie look alike complete with arm tattoos, colourful necklace and pink hair in armpits, reports aceshowbiz.com.

The doll sports similar outfits the 22-year-old wore when she showed off her newly dyed armpits on Friday, including white sleeveless crop top and jean hotpants. It also had the singer's usual blonde pixie cut. The former "Hannah Montana " star captioned the image: "#Selfie."

Cyrus also posted a photograph of her with green armpit hair.

The "Party in the U.S.A." singer photoshopped singer Katy Perry, from "Roar" music video, swinging from her green armpit.

"Katy Perry swannnnginnnn from my pits!!!!" she captioned the image.

Cyrus apparently decided to dye her armpit hair after debuting her unshaved armpit hair in a selfie last month.
