Jennifer Lopez has caused upset at yet another restaurant after making impossible demands. The Love Don't Cost A Thing singer, who was banned from posh London eatery The Ivy after upsetting staff with her diva-like antics last November (2001), took three of her pals to Islands In Westchester, a busy Los Angeles diner best known for its burgers and fries.

According to American tabloid the Globe, J. LO phoned ahead to demand a certain table and a certain waiter, insisting he only attend to her group. Columnist Shelby Loosch says, "When she arrived, the manager explained that they were too busy to allow the waiter to serve her exclusively and ignore the other patrons. Jen started arguing and wanted to leave, but her pals persuaded her to stay. "

But when it came to paying the bill, the angry singer and actress put her money where her mouth is - and left no tip.
