Justin Bieber Twitter: Tweets 'Worst Birthday' After Night Out, #BeliebersHatePaparazzi Trends, No New Girlfriend to Comfort Him?

From tweeting "Big Night Ahead" earlier in the day to "Worst Birthday" just recently, Justin Bieber had left his 35 million Twitter fans around the world worrying and wondering about the birthday boy. What has ruined the night for Bieber?

Bieber almost has it all - money, fame, world records, a mother who would live and die for him, and the largest group of loyal fans called beliebers. What more can a 19 year old ask for? Some might say, a new girlfriend?

Many celebrities took to their Twitter account to wish him a great birthday.

One Direction's Niall Horan tweeted, "Big happy birthday @justinbieber , have a good day bro !"

Label mate Carly Rae Jepsen wrote, "Happy Birthday to an incredible artist and friend.@JustinBieber ~enjoy 19!"

The funny woman Ellen DeGeneres tweeted, "Happy birthday, @JustinBieber! The screaming fans, the Twitter following, the perfect hair -- I'm sorry, I'm thinking of me."

Manager Scooter Braun wrote, "Spoke to the kid and wished him happy bday. He is gonna go hard tonight and well deserved.@justinbieber enjoy your day! Happy 19th Bday!!"

Besides his recent breakup with Selena Gomez, there are many friends and family supporting the pop star.

Naturally, everyone speculates who might be the next girl to capture his heart.

Mstars reported last week that Biebz was actually spotted out with a new girl, whom sources online claimed was his new girlfriend. That girl named Ella-Paige Roberts Clarke denied that she had any romantic relationship with Bieber. Days before that, media spread rumors that he spent the night at his hotel room with a hot young blonde in London.

Let the rumors rest and let's wish Bieber a good rest of his 19th birthday!
