Looks like Selena Gomez's heart still wants Justin Bieber. The Texan beauty, who has just broken-up with her boyfriend Justin yet again, reportedly threw a fit for him at Taylor Swift's recent birthday party, various websites are revealing. Taylor threw an extravagant terrace birthday party at her apartment in New York on Friday, Dec 13 where Selena was also present, among other guests.

While other high profile guests like Beyonce, Jay Z and Justin Timberlake enjoyed the lavish food and drinks, Justin's ex-girlfriend was somewhere else in her mind. She got frustrated over something and became emotional for him, reveals. "She shouted, 'No one understands me! My boyfriend doesn't even understand me," a source present at the party tells the website. Selena's emotional outburst drew attention of all the guests who were present at the party.

"Everyone just stared," the source added, according to the website. However the website also adds that Selena's emotional outburst went unnoticed by the birthday girl Taylor as she was busy having fun with her high profile guests including Karlie Kloss, Chrissy Teigen, Kelly Osbourne and Sam Smith, among others. The "I Knew You Were Trouble" singer turned 25 on Dec 13, 2014.

Meanwhile in her recent interview Selena said that she was very much single and is not dating anyone. When she was asked about Justin, the 22-year-old singer said that she has "love and respect" for him in her heart. Justin and Selena have been in an unstable relationship since quite sometime now. The couple often reunites to break-up soon after. Selena also came out with an emotional song "The Heart Wants What It Wants" from her new collection "For You." The song is speculated to be based on her tumultuous relationship with Justin. Selena gave an extremely emotional live performance of the song at the recent American Music Awards in Los Angeles that even made her best friend Taylor cry in the audience.
