Video Taylor Swift fans notice a ‘hickey’ on her neck while performing in Sweden on Saturday

Taylor Swift appeared to have a massive hickey on her neck while performing in Sweden on Saturday.

When the superstar, 34, took the stage at her Eras Tour concert and swept her hair behind her ear, fans pointed out that there was an obvious kiss mark on her neck.

As seen in fan-taken footage from a concertgoer in Stockholm, several fans speculated it was a love bite left by her NFL boyfriend Travis Kelce, 34.

She had just recently returned to the European leg of her world tour after enjoying a romantic getaway with her boyfriend in Lake Como in Italy.

During her break, the couple stayed at a luxurious €21,000-a-night villa and enjoyed a romantic boat ride, cuddling and making out on the water taxi.

After spending five days loved-up with her beau, the singer returned to the European leg of her ongoing Eras Tour.

Fans noticed the evidence of her romantic and intimate trip as she was sitting at the piano and performing songs from her Evermore era.

Wearing a sparkling blue number, she pulled her hair to one side while singing Champagne Problems and revealed the blatant mark.
