It's a BOY
The second son of Crown Prince Al-Muhtadee Billah and Princess Sarah was born today, June 20th. His full name is:
PENGIRAN MUDA MUHAMMAD AIMAN IBNI DYTM PADUKA SERI PENGIRAN MUDA MAHKOTA PENGIRAN MUDA HAJI AL MUHTADEE BILLAH
I think the given name is Muhammad Aiman. They're keeping sort of a pattern with the names, Muntaqim, Muneerah and now Muhammad, all begining with Mu.
