Kylie Jenner recently took to Snapchat to declare that a make-up mishap was the reason behind her sister Kendall's suddenly plump lips.
But Kendall was showing off a fuller pout once again on Thursday as she celebrated Thanksgiving with Caitlyn and the Kardashian-Jenner family.
Caitlyn, 67, shared a photo to Instagram that evening, which showed her sitting at dinner with her two youngest daughters.
And many of the social media site's users were quick to comment on Kendall's noticeable lips.
The model and reality star, who recently deleted her Instagram, also posed for selfies on her own Snapchat account and her 19-year-old sister Kylie's.
Last week, rumours were sparked that Kendall has had lip fillers after she shared a photo to Twitter which showed her sitting beside Kylie and showing off a huge pout.
However Kylie was quick to come to her rescue, insisting the look was all her fault.
'You guys, Kendall let me over-line her lips today with lip liner and everyone thinks she got lip injections,' the teen confessed on Snapchat.
She added a genuine apology: 'I'm sorry, Kendall!'
Kylie finally confessed to getting fillers to plump up her lips last year, after months of speculation. She now has a hugely successful range of lip kits.
Meanwhile the Kardashians celebrated the Thanksgiving holiday this year at Kylie's home.
