Singer Britney Spears, who has battled alcohol addiction in the past, don't allow her friends to drink when she is around.
Spears dined with a group of eight people at the Four Seasons Hotel in Westlake Village here.
Before Spears arrived, a few people in the group ordered drinks at the bar. They all then went to their table in the restaurant, leaving the drinks behind, reports tmz.com.
The singer has laid down strict laws for friends and do not allow them to consume alcohol in her presence.
According to a witness, a waitress came by and brought a glass of wine that one of the women had been drinking, and apparently in Spears' presence the woman told the waitress was mistaken she wasn't drinking wine.
Once the singer left, all the friends went to the bar and enjoyed drinks.
