Taylor Swift and Calvin Harris' most adorable PDA moments from the Billboard Music Awards

Taylor Swift and Calvin Harris caused a stir at the Billboard Music Awards on Sunday night with a string of adorable PDA moments.

After speculation and rumours the famous pair were dating, they seemed to confirm it at the ceremony and it was just too cute.

From their loving hugs to the way they looked into each others eyes, they looked so happy and relaxed - while Tay Tay's BFF Ed Sheeran's look of pride said it all.

The couple were looking very cosy throughout the ceremony - despite not appearing together on the red carpet.

First there was just the LOOK they were giving each other as they sat next to each other during the bash.

Taylor and Calvin just stared into each others eyes as they chatted and soaked in the atmosphere during her VERY successful evening.

Then there was the constant whispering of sweet nothings, no doubt, as the couple enjoyed a private chat.

We're not sure exactly what they were talking about, but we're sure it was just totally adorable.
