Singer Rihanna is in love. But not with a guy! She has fallen in love with her cousin Noella Alstrom's newborn baby daughter.

The pop star has declared her love for the newborn by posting a number of snaps of herself and the baby on Twitter, reports contactmusic.com.

In one picture, where Rihanna is seen cradling the baby as she enjoys a nap, she wrote the caption: "Guess who fell asleep at the hospital again? #AuntyOhNaNa."

In another photo, which was accompanied by the caption "In Love..." the newborn baby is seen lying on her "aunty" Rihanna's chest.
