The pictures show Noah, 9, and her co-star Emily Reaves from their YouTube show, The Noie & Ems Show, wearing only bathing suits, make-up and carrying handbags.

The two girls were snapped arriving at a pool party for actress Brittany Curran's 19th birthday.

Ocean Up published the photos said news.com.au on Friday.

Commentators in the US have been outraged by the shots, saying it was 'unbelievable that the children were parading around like adults'.

Bloggers and comments running below the images have ranged from admiring to disbelief, reported news.com.au.
