The 15-year-old appeared to be taking after her older sister as she stepped out in West Hollywood.

Noah Cyrus is certainly following in her sister Miley’s footsteps.

The 15-year-old, who watched her sibling transform from sweet Hannah Montana into a twerking sensation, appeared to be going in the same direction when she attended Kylie Jenner’s birthday on Sunday.

While it was expected all eyes would be on Kylie, Noah surely managed to turn a few heads when she rocked up to the bash held at Bootsy Bellows in West Hollywood.

The pretty blonde wore an eye-catching outfit comprised of skinny jeans, a leather jacket, knee-high boots and a cap.

But the teen’s most striking garment for the evening was surely the flesh-flashing crop-top that she was wearing.

The revealing number included large faux rips, meaning that Noah’s chest – as well as her stomach – was on show.

She completed her dramatic new look with black lipstick and dark eye make-up.

It seems that Noah has also inherited her sister’s obsession with taking selfies as she shared a number of pictures on Instagram during the night.

On one picture she wrote: “Happy birthday babe #happy18thkylie.”

Less than one year ago Noah appeared to be blossoming into a lovely young lady when she attended the AMAs in November.

On that occasion she looked a lot different as she posed in a black playsuit.

Since then she’s gone through a startling transformation after dying her hair and experimenting with her make-up and wardrobe.
