Fans were equally excited to see Katy and Lady Gaga reunited on the red carpet as the pair both rose to fame around the same time.

"POP EMERGENCY KATY PERRY AND LADY GAGA TOGETHER," another wrote.
"Seeing Katy Perry and Lady Gaga together feels so surreal... I want them to collab," someone else added.
"Lady Gaga and Katy Perry having a moment together — these two will remain as POP LEGENDS, no matter how the media & critics will find a way to pit them against each other," another said.
While the pair became famous around the same time and were friends, they were pitted against each other and had a short feud in 2018.
Court documents in a legal battle between singer Kesha and producer Dr Luke revealed text messages between Lady Gaga and Kesha where she made some not so nice comments.
Lady Gaga then took to Twitter to set the record straight, writing, "[Katy Perry] & I have grown up in the industry together. We’ve gone through both celebrations & differences w/ each other. These are old texts. We’ve matured, gotten over the past, love each other & share deep respect. Katy is my friend and is truly a kind soul. End of story."
Katy replied, saying, "Love you too friend. Onward and upward."
