Rihanna refuses gift

Rihanna sent back a $10,000 bottle of champagne because she didn't know the people who had bought it for her.

However, Rihanna refused to accept the gift because she had no idea who they were.

One partygoer said: "She didn't know who they were, so she sent it back."

While Rihanna is bought drinks when she goes out, Kiefer Sutherland buys his fans a beverage.

The ‘24' actor stunned bar staff when he bought all of their customers a drink after he and some crew members of the hit US drama series popped into The Spot in San Pedro, California, after finishing a shoot at seven in the morning.

According to an employee, Kiefer was enjoying scotch and cokes and decided to buy everyone in the venue - about 30 people - leaving him with a $500 bar bill.

He then gave staff an impressive $200 tip when he left.
