This is so precious!!
But now, we have picture proof!
The proud parents (minus Prince George) posed outside St. Mary's hospital for all to see.
They're positively glowing! We can't wait for an updated family portrait to be released!
Justin took the stage with some of his hits, including Baby, as well as some tracks off his latest album, Believe!!
Check out JB (above) with his acoustic serenade of Fall!
Aww… wonder if he was singing it to Selenita!
Bieber also got the crowd pumped up with his fancy footwork, when he took on All Around The World!
