The '22' singer was a notable absentee from this past week's festivities as the 'Come And Get It' star turned 21.
Taylor Swift apparently rejected the chance to go to Selena Gomez's birthday party because Justin Bieber was going to be in attendance.
The 'We Are Never Ever Getting Back Together' singer is said to have avoided the celebrations in favour of a quiet night.
"Taylor isn't mad that Selena's party was in LA. Taylor has been busy and will celebrate with Selena sooner than later and has contacted her to wish her a Happy Birthday, but she would have avoided going to the party because she would know Justin was there and she isn't a super partier," an insider told Perez Hilton.
"She is actually happy that she was busy so she had an excuse to avoid the hoopla herself as she would avoid the drinking and the carrying on. Taylor is very much a homebody and a little reserved so she is not to torn up that she missed out."
Taylor is currently on the road with her 'Red' world tour and was performing on the East Coast at the time.
The country singer was also seen pulling a face at an embrace between Justin and Selena backstage at the Billboard Music Awards 2013.
Meanwhile, Selena recently confirmed that she is no longer dating Justin Bieber despite rumours of a reconciliation between the pair.
They ended a near two-year relationship at the end of 2012.
