Is there really a feud going on between Taylor Swift and Kendall Jenner? Could it be true that Gigi Hadid and Selena Gomez have taken the side of the Victoria's Secret model?

Rumor has it that the fact that the "Take It Off" singer was not around during the 20^th birthday party of the daughter of Caitlyn Jenner and Kris Jenner already signaled that something not right was going on.

Hollywood Life reported that while the model was having her "star studded" birthday dinner at The Nice Guy restaurant, the 25-year-old multi-awarded singer and songwriter was also having hers nearby.

However, it can be noted that Taylor Swift's birthday would still be in December. Could it be that she was not really invited by Kendall Jenner? But why were Gigi Hadid and Selena Gomez spotted in the model's party and not in hers?

"Perhaps Kendall didn't invite Tay Tay but the singer actually had her own birthday party to attend at The Little Door up the street," the report said. "Awkward!"

Hollywood Life added that there have been speculations that their friendship has been tainted "after they both had a thing for Harry Styles."

In the meantime, Celeb Dirty Laundry shared a "Star Magazine" report in July saying that Taylor Swift allegedly "bullied" Kendall Jenner and Gigi Hadid.

When the models were invited to appear on her concert at the Hyde Park Stadium, the singer had a number of demands which reportedly did not sit well with them.

"Taylor had a dress code for everyone to make sure that she wasn't upstaged," a source revealed. "They were told to stand a certain number of feet behind Taylor at all times, not to speak unless spoken to, and not to discuss Taylor's personal life in interviews."

The source continued by saying, "Gigi was talking trash behind Taylor's back, she got Cara and Kendall all riled up."
