Katie Price sore with new plumped up pout

Updated: 

She's famous for her trout pout, but Katie Price has admitted the plumped up look comes at a cost.

Model Katie revealed that she had had a new lip filler procedure, but that she was feeling the burn from the injections still.

According to The Sun, Katie greeted fans at her "Evening With" event at the Glasgow Hilton Hotel, where she is promoting her seventh autobiography, Reborn, and said of her mouth: "It's sore. But it won't kick in for a while."

The mum of five also showed off her new pout on Instagram, starting with a video of herself getting ready for a pampering appointment captioned: "Here I am back in Manchester at my favourite @macaesthetics with Rebecca. The best Wooooooooo X" which included emojis of a syringe and a pair of lips.

Later in the day, she proudly debuted her finished look.

Katie, 38, could't resist one more shot, which she captioned: "Enough about my lips lol."

During her autobiography promo event, she told the crowd that she plans on doing another glamour calender, saying: "You don't make any money from it but I enjoy doing it. It's an excuse to get the kit off."

Katie isn't the only celeb to be suffering a sore face today - her ex Peter Andre also Instagrammed photos of his bloodshot eyes, admitting they were burning after he had mistaken wife Emily's eyelash growth serum for eye drops.
