reached the age of 20 on Saturday, March 1 and he chose to celebrate it with a low key party surrounded by his family. Justin's father Jeremy Bieber flew to the pop star's new home in Atlanta, Georgia with his other children, 5-year-old Jazmyn and 4-year-old Jaxon, for some family time.
"Happy Birthday son. Wow 20!" Jeremy, who reportedly just separated from his younger children's mother Erin Wagner, tweeted. Justin's mom Pattie Mallette, who split from Jeremy when Justin was 2, also tweeted, "Happy Birthday YOU KNOW WHO! I love you. Xoxo". Justin himself tweeted a smiley face. Earlier this week he wrote, "Bday week. wish the world would learn to believe in the goodness in people and be kind to one another. together we can change the world :)".
