Taylor Swift wants Selena Gomez to cut all ties with Justin Bieber.

The I Knew You Were Trouble singer - who is single following her split from One Direction star Harry Styles in December - is encouraging her best friend to move on because she doesn't think the 18-year-old Canadian popstar is right for her.

A source close to Taylor, 23, told HollywoodLife.com: "Taylor would rather Selena break everything off with Justin and believes that will happen in the very near future. Taylor isn't a Justin fan at all. There is just a process that Selena has to go through to have that finally happen and Taylor understands that.

"Taylor is very spiritual and superstitious and believes in the saying, 'It takes half the time of a relationship you had with someone to get over the relationship you had with that person.'

"If Taylor can speed things up a little bit by being there for Selena and showing her the fun she can have, then she will gladly do it."

Selena, 20, is reportedly back on "good terms" with her on/off boyfriend of more than two years, despite dumping him more than a month ago.

A source told E! News that although they have been spending time together again recently, things between them are "complicated."

The couple broke up shortly after holidaying in Mexico where they had planned to ring in the New Year together but got into a huge argument on December 30 after she allegedly found text messages from other girls on his phone.
