Nick Jonas makes booze delivery to fans

Pop star Nick Jonas surprised fans by turning up at a party with a drinks delivery and performing for them.

The former Jonas Brothers singer took over the alcohol delivery app Saucey in Los Angeles, and shocked partygoers by turning up with their alcohol order before playing his hits Jealous, and Chains.

One of the guests at the party took to Instagram.com to share her excitement, writing, "Nick Jonas just casually playing Jealous for me. After we shared a bottle of wine. Is this life????? Thank you Saucey, Nick, and the universe."

Jonas is an investor in the app and a representative for Saucey tells People.com that the star wanted to meet some of his customers.
