"Majesty is a feisty one, just like all the woman in my family," Rihanna smiled. "She already has her personalities. It's so cute."

The 27-year-old also spoke about her new music, promising fans they won't have to wait too much longer.

"The album is coming soon!" she teased.

The star is set to be busy on the music front, as she recently announced she'll be hitting the road with her rumoured boyfriend Travis Scott.
