'Heartbroken' Taylor Swift

Taylor Swift will be "heartbroken" if Harry Styles just wants to be friends.

The 'Shake It Off' hitmaker and the 20-year-old One Direction star - who split in 2013 after a brief romance - have reportedly become friends again, with insiders revealing that Taylor wants more.

A source said: "If Harry is just trying to be friends and he has no plan to actually date her again, this is going to be hard for her.

"She's going to get her heart broken all over again. She's just so sensitive and she does still like him a lot."

However, Taylor may be disappointed as another insider has explained that Harry just wants to keep his relationship with the 24-year-old singer platonic.

They told HollywoodLife.com: "There's not a chance in hell that Harry will date Taylor again. He's a nice guy and wants to be friendly.

"He holds no grudges, but he doesn't want to be in a relationship with Taylor again.

"It didn't work out and wouldn't work out if they tried it again. He knows that it would be a disaster."

Rumours that the pair are reuniting started when reports surfaced that the 'Steal My Girl' hitmaker sent his ex 1,989 red roses to congratulate her on the success of her new album.

Sources also confirmed that the pair "have become pals" again and Taylor was even believed to have bragged "to her trainer and celeb friends that she and Harry are talking again".
