Harry Styles, the hot 'This is Us' star, may regret letting Taylor Swift go. The cute One Direction singer and Tumblr favorite may reunite with the "Sweeter Than Fiction" singer.

According to a Look Magazine report, the British crooner, 19, is having second thoughts about his break up with Swift, 23.

Hollywood Life believes the report suggested that the "22" singer and Styles just can't stay apart. The former twosome reportedly had a flirty conversation during this year's MTV Video Music Awards, where Swift dissed Styles twice and then posed for a photo with him at an after party on Aug. 25.

Reportedly, Zayn Malik's bandmate could be open to rekindling their romance after the pair had a honest conversation during the awards night.

"Taylor and Harry had a heart to heart," a source told Look. "He's very funny, so can make her defenses come down very easily. He told her that she was the most stunning girl at the awards and that he was mad to let her go." 

It looks as if Ed Sheeran's friend may give their relationship another go.

"They're planning another dinner when they're in the same city," the source continued. "Taylor's happy to be back in touch with him, as they have a lot of laughs together but she was hurt and she's cautious of going there again." 

If the couple got back together, their reunion may be quite shocking given that Swift openly writes break up songs about Styles. And fans cannot forget that Swift disrespected Styles at the recent MTV awards.

The blonde singer reportedly whispered "Shut the F***" up" to Selena Gomez while 1D was presenting an award. She also reportedly called Styles out during her acceptance speech that night.

"I also wanna thank the person who inspired this song, who knows exactly who he is, because now I got one of these!" Swift said during her speech for winning Best Female Video for the song, "I Knew You Were Trouble."
