Pop princesses: Kylie Minogue, looking stunning in a see-through floaty dress and over-the-knee boots, and Katy Perry in a funky rubber dress and purple wig, perform at the final of Germany's Next Top Model in CologneShe may only be a tiny 5ft 1in but Kylie Minogue knows how to give the catwalk queens a run for their money.
With the help of her dancers - and some very high-heeled, over-the-knee cream lace-up boots - she towered above the stage as she performed in Cologne last night.
The pint-sized pop star, who teamed her legwear with a very revealing floaty dress, was one of the guests at the final of Germany's Next Top Model.
Surrounded by a number of half-naked dancers, the Australian singer, 42, treated her German audience to a performance of her new song All The Lovers.
Emulating the video for the single, which is released this weekend, her male and female dancers writhed around in a giant human pyramid with Kylie singing on top, her blue print dress billowing around them.
She certainly showed how it was done to her younger pop counterpart Katy Perry, who was also on last night's line-up and brought her own sense of fashion to the night.

On top of the world: Kylie towers over her dancers, who stripped off halfway through the songThe I Kissed A Girl star, 25, swapped the electric blue wig she wore at last weekend's MTV Movie Awards for a purple one as she took to the stage.
Performing her new song California Gurls, she was her usual kooky self in a short rubber dress that looked like it had pieces of Lego printed on it.
She was giving a warm reception from the audience at the Lanxess Arena, and in typical fashion took to her Twitter afterwards to gush about the night.
