“She’s tired and overworked and acting sullen and rude to people around her – even her own family!"
A pal explained exclusively to RadarOnline.com the reality star-tuned-model has been working nonstop over the past four years, which has understandably added to the stress.
"She’s constantly dieting and she’s unhappy with her love life," revealed the snitch. "That’s made Kendall increasingly irritable."
The pressure on the 23-year-old supermodel has said to have given Jenner a nasty attitude. "She’s not minding her manners and swearing a lot. Kendall used to be so sweet."
"Now, even her own sisters have had enough of her bad attitude and telling her to take care of herself and get some R&R.”
