Taylor Swift

It is the first time Mr Mueller has spoken about what happened backstage at a Detroit concert in 2013.

Taylor is suing him for assault and battery over the incident, which she says left her "shocked and withdrawn".

He denies the claim that he grabbed her "bare bottom" under her skirt.

The ex-DJ was fired from his job at a Colorado country music station after the encounter and has now spoken about the legal case with Detroit radio show, Mojo In The Morning.

The track is called Better Man but she won't be singing it herself - it's been penned for country band Little Big Town.

"But your jealousy, I can hear it now," go the lyrics, "you're talking down to me like I'll always be around".

"You push my love away like it's some kind of loaded gun" she also writes.

The band has confirmed in a Facebook Live Q&A that Taylor is behind the track.

"She sent us this song, and it was one that was really special to her," singer Karen Fairchild explained to fans.

The prolific DJ/producer talked to British GQ about his 15 month relationship and subsequent split with the pop star.

Harris told the publication "It's very difficult when something I consider so personal plays out very publicly."

"We began The 1989 World Tour in Louisiana, and the wonderful fans there made us feel completely at home," Swift said in a statement to CNN. "The fact that so many people in Louisiana have been forced out of their own homes this week is heartbreaking. I encourage those who can to help out and send your love and prayers their way during this devastating time."

Louisiana Governor John Bel Edwards has declared a state of emergency in the wake of the disaster that has damaged at least 40,000 residences.

Those who care have long suspected that Taylor Swift's song "Back to December" was written about her 2009 relationship with the actor.

Now, the "Twilight" star is confirming that he was indeed the inspiration for the pop star's 2010 hit.

Lautner got put on the spot by his "Scream Queens" co-star Lea Michele during a Facebook Live session on Monday. As their conversation turned to the two Taylors dating, Michele asked if Swift had written a song about him.

"That's what she does," Lautner said. "She writes songs."

Partygoers at a birthday celebration in the Hamptons over the weekend were treated to quite the treat when Taylor Swift and Nelly came together to perform the rapper's 2002 classic, "Dilemma." In multiple videos shared online, the Grammy winner can be seen having an absolute blast onstage with her newfound duet partner as she takes on Kelly Rowland's part in the song.

But so are some of the difficulties she has had with fellow stars.

Swift's current feud with Kim Kardashian West and her husband, Kanye West, is merely the one everyone is currently talking about.

To be fair, Swift is one of the biggest stars on the planet. So just about any skirmish she's involved in becomes a "thing."

Here are a few of Swift's high profile beefs.

It is after Kim posted a series of videos appearing to show her husband talking to the singer about his track Famous.

They claim the footage proves Taylor had approved a controversial lyric about her.

However, the 26-year-old's released a statement saying, "you cannot approve a song you haven't heard".

This is the latest development in a high profile three-way feud involving the world's biggest popstar, rapper and reality star.

"Look, the truth is that Taylor Swift and I are together, and we're very happy," the actor told The Hollywood Reporter Thursday. "Thanks for asking. That's the truth."

Rumours had been circulating online that she was the lyricist behind This Is What You Came For, which features Rihanna.

Swift's representative confirmed it to People magazine, which the DJ retweeted from his official account.

He wrote: "Amazing lyric writer and she smashed it as usual."
