Taylor Swift's Grammys performance of "All Too Well" described a rough relationship between a frustrated female and persistent male, leaving many fans wondering if it may have been about best friend Selena Gomez's relationship with Justin Bieber.

"You call me up again just to break me like a promise/So casually cruel in the name of being honest," she sang.

However, rumors also speculate the song may have been about ex-boyfriend Jake Gyllenhaal.

Lorde revealed during a recent interview that her and Taylor Swift, who is allegedly upset at Selena Gomez for her reconciliation with boyfriend Justin Bieber, are excellent friends.

"Taylor's super good at this stuff," Lorde told PEOPLE magazine while explaining her preparations for the "Red" singer's 24th birthday.

"She's decorated her whole house for ages." 

"There are very few of us," Lorde added in discussing young female singers.

"The other teenagers sing other people's songs, which is fine, but it's not an authentic teenage experience." 

Lorde captured the attention of many when she called Selena Gomez's music "anti-feminist."

Taylor Swift is allegedly angry at Justin Bieber and Selena Gomez for getting back together, Fashion and Style reports.

The "Red" singer and Selena Gomez are known to be childhood friends, but may be sacrificing their relationship with the "Heartbreaker" singer back in the picture.

"Selena had been staying at Taylor's home for rest and relaxation, but the two had a blow-up after Selena admitting to being in secret contact with Bieber since before Christmas," a source told the website.
