Rihanna and Jay-Z rolled into town last night and immediately made waves by racking up a huge bar bill at Mayfair club Vendome.

Avoiding questions: Rihanna

The pair and their respective entourages set up camp in the VIP area, where they had soon totted up a tab of £7,000.

Thumbs up: Jay-Z clearly approves of Vendome

We're told: “They had two of the VIP booths, so all of their people could mingle together. Jay–Z ordered countless bottles of Dom Pérignon champagne along with vodka for both tables and the party really gathered pace.

“Everyone was trying to get into their area to get a glimpse of them but the security was so tight, many were left standing by the roped off area trying to sneak a peak.”

Singer Rihanna's altercation with former boyfriend Chris Brown as highlighted again yesterday when he appeared on a YouTube video apologising for assaulting her.

In it, he said he had repeatedly apologised to her and insisted he would have said sorry sooner — but his lawyer told him not to. It didn't seem to have any effect on Rihanna last night.

Our spy added: “As she walked out of the VIP area she looked in high spirits. But she kept her head down as she made her way out of the club at 3am, avoiding questions from fans as to how she was doing.”
