Harris is doubtful over it after he learned that she liked a Tumblr post about the One Direction singer.
According to a source, Harris doesn’t like Swift’s social media move and wants her to focus on their relationship, reports hollywoodlife.com.
“Calvin has separated himself from his playboy ways and is all in with his relationship with Taylor,” a source said.
The source added: “He doesn’t like when she mentions her exes. He wants her to not talk about them, even if it’s her throwing shade at them. (Calvin) wants her to be totally devoted to him. He gets jealous thinking that she still may have feelings for people like Harry or others she has dated – it’s upsetting to him”.
The report came after Swift threw shade at Styles by liking a Tumblr post which said that he was “immature” when they dated.
