Taylor Swift allegedly set up Selena Gomez and Austin Mahoney's rumored date, leaving many fans wondering if she's get into problems with Justin Bieber.

"They're seeing each other," a source close to Taylor Swift told Us Weekly.

On Jan. 24, after the Beats Music concert, they "sneaked out separately, then got in the same car," HollywoodLife.com reports.

Taylor Swift was spotted at the Grammys with Lorde and several other close friends except for Selena Gomez.

Selena Gomez was also rumored to have spent her night along in her Los Angeles home.

Taylor Swift's Grammys performance of "All Too Well" described a rough relationship between a frustrated female and persistent male.

"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."
