Kicking off the weekend a bit early, Rihanna made her rounds in Capri, Italy with a few friends last night (July 19).

The "Umbrella" singer arrived in the gorgeous Italian city via her yacht Latitude and grabbed some dinner at the exclusive Il San Pietro restaurant.

And it sounds like Rihanna (24) has been keeping some seriously crazy hours as of late, causing the staff on her boat to grow weary.

An insider told press, ''The gang stayed up singing and dancing until dawn. She's a lovely girl but the crew are only getting a few hours sleep a night. And they have to be prepared to be vigilant and make sure she doesn't get hammered and fall into the sea.''

Enjoy the pictures of Rihanna out to dinner and heading out to a yacht in Capri (July 19).
