While there's no doubt that Taylor Swift is a woman who likes to move fast, who knew she was this fast! While the celebrity world seems to be rather shocked that the chart topper is supposedly now dating British actor Tom Hiddleston, there's one person in particular who seems to be very surprised by the news, and that's her ex-boyfriend Calvin Harris, who the singer just broke up with earlier this month.

According to People Magazine, even though the split between Swift and Harris was amicable, critics can't help but throw a little side eye toward the singer after she was supposedly spotted getting up close and personal with Hiddleton this past week. What's more, Harris had no idea that the two were even an item.

One source close to the DJ said, "He did not know Taylor and Tom were together," before adding, "He's moved on and is happy. There was no drama or cheating. Things just don't work out sometimes."

Yet, fans don't seem very convinced as some have commented on Swift's new romance with, "Seriously any woman with an ounce of self esteem would be comfortable staying single for longer than a few weeks. Dating is fine; jumping from one relationship to the next is a sign of neediness and instability," along with, "Rebound!! I sense some bad blood between those two."

Another critic wrote, "She bounces from man to man. What a lonely sad girl and her millions will never make her happy."

So far, neither Swift nor Hiddleston have made any comments about their new relationship. Keep up with Enstars for all the latest updates on Taylor Swift and all of your favorite celebrities right here.
