A week after their romance was outed when they got snapped smooching on a beach in Rhode Island, Taylor Swift and Tom Hiddleston were caught kissing yet again -- but this time from the stands at Selena Gomez's concert in Nashville, Tennessee on Tuesday. They're so public about their new love!

A source told E! News, "Taylor invited Tom to go. Tom always wants to please Taylor and show her that her friends matter. Taylor likes that about Tom."

Many people are shocked to see Tay move on so quickly after her 15 months with Calvin Harris -- while many have speculated that she actually cheated on the Scottish DJ with the Brit. However, Us Weekly is reporting that the Night Manager actor began to court Taylor, whom he'd met at the Met Gala, only after he'd heard about her split with the EDM star. A close source told the outlet that, “he started reaching out,” in early June.

Either which way it sounds like it's a good thing Tayvin is over …
