Rihanna has shared her joy at becoming an aunt by publishing a series of candid snaps showing her cradling her newborn niece.

The Umbrella hitmaker published a photograph on Twitter.com showing herself holding the little girl in what appears to be a hospital unit on Sunday night (08Jun14), adding in a caption, "My everything."

She added a succession of shots which showed her lying on a bed, holding the baby to her chest, adding, "My auntie rule$ (sic)... I can't get enough, I'm so in love."

No more details about the baby's parentage were available. Rihanna has two brothers as well as two half-sisters and a half-brother.
