Paris Hilton has been spending time visiting orphans in Bali during her week-long vacation in Indonesia.

The socialite-turned-TV personality jetted to the south-east Asian country for a lavish holiday and enjoyed a spa retreat with her girlfriends.

But she made sure to give back during her trip by paying a visit to two orphanages in Bali, where she greeted staff and played with children.

Hilton also posed for photos with the orphans and took to her Twitter.com page to encourage fans to donate to the non-profit organisation Yayasan Kasih Peduli Anak, which provides housing and education for street kids in Bali.

She tweeted, "Had a great day spending time with the orphans from 2 of the orphanages in Bali. Such sweet, beautiful children. Loved seeing them smile.

"The orphans of Bali need your help. Make a difference. Change a child's life."
