Justin Bieber turned 20 on Saturday, March 1st, and he got a lot of love from his friends and family on Twitter. The star retweeted birthday well wishes from Carly Rae Jepsen, his manager Scooter Braun, his parents and his Shots app business partner Johnny Shahidi.

Shahidi posted a photo of Bieber blowing out candles on a cake on Instagram (pic above) that said, "Happy Birthday Bizzle."

Bieber's mother, Pattie Mallette, tweeted, "Happy Birthday YOU KNOW WHO! I love you. Xoxo . . . 20!? I haven't accepted it yet. Still in denial! I can't believe it! Not a teenager anymore . . . Unbelievable. #DoesThatMeanImOldNow?."

His father, Jeremy Bieber, tweeted, "Happy Birthday son. Wow 20!"

His rumored girlfriend, Chantal Jeffries, posted a tribute to the singer that said Happy Birthday in French, "Joyeux anniversaire." The post also included a photo of the couple but it was later deleted.

Bieber was very secretive about how he planned to celebrate his birthday and that may because he wants to keep a low profile.
