The British star celebrated her 28th birthday at a Mexican restaurant in London on Saturday.
Kelly dressed up for the meal at La Bodega Negra, but says the temperature of the restaurant caused a bit of a beauty blunder.
"trying 2 find a nice pic of me on my birthday but my face is so red in them cause it was so hot in the restaurant I sweat all my make up off (sic)," she complained to her followers on Twitter.
Kelly and her party moved on to a club after their meal at the exclusive restaurant.
The star wore a black and silver sparkly dress and heeled brogues in honour of the festivities.
A cute ponytail and large clutch bag finished off the pretty star's look, as she linked arms with British radio host Nick Grimshaw during her night out.
Whereas Kelly looked gorgeous at her bash, she was less than impressed with the snaps taken during the evening.
"I literally look like i just ran a marathon in every picture (sic)!" she posted on Twitter. Fans responded to the star's tweets with positive comments, assuring her she still looked great. "Who cares about that :) What matters the most is that you had a good time :) (sic)," one posted in support.
