Liam Payne, Danielle Peazer Dating, Break Up 2013 [PHOTOS]: One Direction Singer 'Struggling' Since Split with Ex-Girlfriend, 'Fame Can Be Lonely'

One Direction are currently taking the world by storm with the "Take Me Home" tour and riding the success of the recent single "Best Song Ever." Unfortunately, that doesn't seem to help with the loneliness that fame can bring. According to some sources, Liam Payne is not enjoying the single life after splitting with his girlfriend Danielle Peazer earlier this year. Insiders also say that he wants her back!

"He's struggling with fame since he split with Danielle. He's admitted he feels really lonely without her; she made him feel sane amid the madness," a source recently revealed to Heat magazine. "He wants her back, but he won't get a chance to see her soon."

Lonely Liam will be heading on to Australia for the final leg of the gigantic tour alongside his band mates Louis Tomlinson, Harry Styles, Zayn Malik and Niall Horan. This means that the young heartthrobs won't be returning home until the end of October.

With the exception of Niall, who seems to be handling the single life better than Liam, the rest of the One Direction boys are in or rumored to be in relationships. Zayn Malik is dating Little Mix singer Perrie Edwards and Louis Tomlinson is dating model Eleanor Calder. Harry Styles has been romantically linked to model Kara Rose Marshall.

Tomlinson recently opened up about how lonely fame can be, and was possibly giving some insight into Liam's struggles.

"It could definitely be a lonely job. I wouldn't be able to do this if I were on my own," Louis explained to Teen Vogue.

Mstars recently reported on Danielle Peazer's struggles with death threats and cyber bullying despite her split from Liam. Here is an excerpt:

"I've been called all sort of names - horrible, racist words that you can't imagine someone saying to another person," the model and dancer shared.

"And I've had a few people saying 'I'm going to cut and kill you'. I can't really get my head around why people think that's okay," she added.

But now that she and Liam have called it quits, you would think the abuse would stop, right? Unfortunately that is definitely not the case for Danielle.

"I probably get cyber-bullied three to four times a day but I ignore it now," she continued. "If I took all of it to heart, I'd never leave my house."
