During KIIS FMS Jingle Bell concert Taylor Swift had a secret visitor.

It was none other then Taylor Lautner, hunk of the Twilight saga films.

The concert was held in downtown Los Angeles.

But it seems that no one back stage was aware that he was there.

But he was spotted by an E!Online reporter. This is reportedly what happened during the evening.

Lautner arrived via a private entrance at the Nokia Theatre L.A at around 8:45 pm.

He reportedly arrived alone and went straight for Taylor Swift’s dressing room.

When he got there the two reportedly acted like a couple. Lautner spent most of his time with Swift , but he was also seen talking to Swift’s mum and other people around her.

The source has said “Taylor’s mom was constantly smiling around him,”

Lautner watched Swift’s performance from the side of the stage as he didn’t seem to want his presence there known.

Lautner is due to host Saturday Night Live next weekend and as of yet there is no word as to whether Swift plans to be there or not.
