Junior Andre prompted tears among his social media followers as he shared an update on his and sister Princess' recent dash to Australia.
The siblings' dad Peter previously told how his eldest children went from meeting their new baby sister to the other side of the world to visit his mother.
The Mysterious Girl singer took to Instagram earlier this month to express his pride in his teenage children for their support.
In an emotional post, Peter, who welcomed a baby girl with wife Emily on April 2, posted a video of his daughter, 16, and son, 18, at the bedside of their 88-year-old grandma, Thea.
