Rumors are starting to pile up about singers and songwriters Taylor Swift and Calvin Harris. According to a source who told the Heat, the two are dating exclusively.

On Sunday, March 8, Swift flew from New York to Las Vegas with friends Ellie Goulding, Selena Gomez and the Haim sister on a privet jet. The Heat source said, "Calvin actually chartered the jet to fly Taylor and her mates over to see him in Las Vegas. Ellie, Selena and Hail all joined her for the trip and they had a great time."

Harris had been in Vegas at the time to play a gig at the MGM Grand nightclub, Hakkasan. The "Blank Space" singer's trip totaled over 2500 miles just to see him. Swift confirmed her appearance in Vegas through social media by posting a photo and her and her friends on Instagram.

Harris, 31, and Swift, 25, had also been hinting that they are looking for romance in February at The BRIT Awards. According to many sources, the couple had been flirty all night, constantly at each other's side during the entire event.

An eyewitness told Radar Online that they held hands at the after party and had a great time together on the dance floor. Harris, who is also a DJ, had just broken up with his long-time girlfriend shortly before the night of the awards.

The Sun reported of Harris' breakup, "They were both into each other for a long time but it just didn't work out, and they'll stay friends."

Now that Harris is single, it looks like Swift is making her way into his heart with both flirting and flying. The two have yet to confirm these dating rumors.
