STRICTLY Come Dancing rehearsals have been thrown into chaos courtesy of the sizzling temperatures in the UK capital.
The BBC show's professionals were captured looking exhausted outside their London training venue - with four air conditioning units being wheeled in to cool things down on Monday.
Karen Hauer, who wore all-black, told her Instagram fans she was: "Leaving rehearsals like… so darn hot!"
She was struggling to combine their intense routines with the searing summer heat alongside Luba Mushtuk and Nikita Kuzmin.
Fellow Strictly dancers Jowita Przystal, Johannes Radebe, Kai Widdrington and Lauren Oakley were also seen taking a cooling break outside.
Jowita - who was seen looking cheery in rehearsals with TOWIE's Pete Wicks last week - covered up from the direct sunlight with a bandana.

Luba donned a black crop top and leggings for her day of training, which came after she was seen practising with DIY SOS star Nick Knowles.
Inside the venue, Gorka Marquez was seen topless as he perched on a stage.
The bunch had gathered to celebrate backing dancer Joshua Keefe's birthday, with Lauren then filmed presenting him with a Colin Caterpillar cake.
They all looked glad of the break as they stuck it out in the sweaty venue.
