Britney Spears banned her entourage from drinking at the same table as her.

The 'Work Bitch' singer has been determined to stay sober ever since leaving rehab in 2007 and refuses to let her friends drink alcohol at the dinner table with her, which allegedly became a problem during a gourmet meal at the Four Seasons Hotel in Westlake Village near Los Angeles last night (07.10.13).

The mother-of-two was joined by her boyfriend David Lucado and six others at the plush hotel bar and insisted the group leave their pre-dinner drinks behind before moving through to the restaurant area.

However, the situation soon turned awkward when a waitress brought over a glass of wine one of the women had been forced to abandon. Britney's friend had to send the beverage back and insist she wasn't drinking, much to the surprise of the waiting staff.

According to TMZ, the strict booze ban was ''too much'' for the pop princess' entourage to take, and the second she retired for the night, they hit the bar hard.

One man in particular made a beeline for the hard liquor, and reportedly got ''wasted'' by ordering three vodkas in rapid succession.

This isn't the first time Britney has banned all alcohol from her sight. During her time as an 'X Factor' judge in 2012 it emerged her team make sure all alcohol is removed from her hotel rooms and TV sets before she arrives.

A hotel rider for the 31-year-old star stated: ''Very important: We require you to empty the minibars of all alcohol. And no gifts of wine or any other alcoholic beverages, please.''
