Last week, One Direction's Harry Styles and his former girlfriend Taylor Swift once again sparked rumours of rekindling their romance, and now an eyewitness has come forward claiming that the couple was recently spotted out and about having a good time.

As per an ETOnline source, the two singers were spotted together at The 1975′s concert at The Palladium in Los Angeles on 19 November, and it wasn't a chance encounter.

"I was on the floor and I saw them in what I believe was a VIP section," the source told the outlet. "They were both dressed in black and they were very friendly towards each other."

"To me they seemed like friends…I'd say somewhere in between," the source continued.

Ever since their break up in 2013, Styles has been a source of inspiration for many of Swift's songs, including "I Knew You Were Trouble," and "We Are Never Getting Back Together." Although many of her exes have expressed displeasure at Swift writing songs about them, Styles recently said that he considered it an honour.

"We write from personal experience, and I think everyone does. So it would be hypocritical of us to be like, 'Oh you can't write songs,' And she's really good, so they're good songs. So, I'm lucky in that sense," he said, according to NY Daily News.

Although it remains unknown what caused their split, a source close to the singer said Styles' roving eyes were the main cause. The couple reportedly went their separate ways after Swift caught him cheating on her. The 24-year-old singer is said to have seen pictures of Styles making out with a friend, following which she immediately called off their romance.

In the meantime, a HollywoodLife source rubbished romance rumours stating that Styles doesn't see a future with the American singer.

"There's not a chance in hell that Harry will date Taylor again," the insider said. "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."
