According to US gossip site Radar Online the 18-year-old heart-throb grew increasingly frustrated with Taylor because of her prudish ways in the days leading up to their split.
A source revealed to Radar that Taylor is nervous about how she is seen by the public so she won't "put out".
They said: “Taylor is so concerned that the public will think she’s a wh*re because she dates around, that she doesn’t put out, what she doesn’t get is that the guys keep dumping her because she’s being a prude.”
Another insider reportedly told Radar that Harry got bored by Taylor, 23, constantly talking about antiques.
And it seems that it was their differing lifestyles that eventually drove the couple apart after just 65 days together.
The source added: “Harry wants to go out to fancy bars and clubs and enjoy being young – but Taylor’s more of a homebody and all she would talk about was antiques!”
“It drove him crazy, so he gave her the elbow!”
