Selena Gomez visits children's hospital in Los Angeles

American singer-actress Selena Gomez made a surprise appearance at a children's hospital in Los Angeles on Wednesday and spent some time with the sick children.

Wearing a white top, black pants and a wide-brimmed hat, Gomez went to the Children's Hospital Los Angeles to talk to the children and their families, reported Ace Showbiz.

Gomez, 22, then took to Instagram to share some photos from her visit. One photo shows her posing with a girl whom she calls "princess". Another photo shows her talking to a boy who sits on his bed while Gomez rests her head on her hand.

The Come & Get It singer also took to Twitter to share her excitement while visiting the children.
