Tom Hiddleston is not worried about Taylor Swift kissing oil heir Mike Hess as he 'trusts' her – report

Tom Hiddleston is reportedly not worried about girlfriend Taylor Swift occasionally mingling with another man while he is not around as he "trusts" the Blank Space hit-maker. This comes after the songstress was spotted kissing oil heir Mike Hess at his birthday party in the Hamptons, New York, on Saturday (6 August).

"Tom [Hiddleston] is more than confident that everything is going very well with Taylor [Swift] . He doesn't worry about her going elsewhere," a source told HollywoodLife. "Tom trusts Taylor very much!"

The party which took place at supermodel Karlie Kloss and Hess's joint birthday party saw the 26-year-old singer performing a duet with Nelly. Swift sang the part of Kelly Rowland from Nelly's 2002 hit song Dilemma.

A video from the party which surfaced on social media, shows the singer plant a kiss on the cheek of Hess, who is a Harvard Business School graduate. Next, they can be seen dancing with Hess's arms wrapped around the singer's waist.

A source told E! News although the British actor was not present at the party "Taylor was in an amazing mood, and super fun all night. She danced her ass off. At first she didn't want to perform but then Nelly asked her. Everyone was super into it, the crowd loved it".

The website reported that the despite mingling with Hess early on, the singer spent the rest of the night with her pal Karlie Kloss.

Swift and the Thor actor started dating earlier in June, just days after the singer split from Scottish DJ Calvin Harris, who she dated for 15 months.

The 35-year-old actor is currently filming Thor: Ragnarok in Australia.
