Rihanna and baby niece support their favourite NBA team

Showing their support for their favorite NBA team, Rihanna and her cousin Noella Astrom's newborn daughter donned Miami Heat jerseys to watch the NBA Finals on Sunday (June 15).

The "Diamond" songstress posted some photos online with captions like "Twinzies" and

"King," but unfortunately the Heat suffered defeat and the San Antonio Spurs were named the new NBA Champions.

Earlier in the day, Ri-Ri kept her fans glued to their smartphones as she uploaded pictures of her
feeding the little lady with a bottle.

Rihanna cuddled the bundle of joy and wrote the message, "Majesty x Aunty OhNaNa," indicating her own new moniker.
