News of the World reports Britney Spears was ordered by new pal Paris Hilton to ditch her underwear and the pair locked themselves in a hotel bathroom for 20 minutes. “Paris loves the fact that Britney gets turned on by going commando,” an insider revealed. “She even demanded that Britney take her knickers off in front of her. Britney just obeyed.” Britney’s initial post-divorce meeting with the heiress prompted a private moment in the loo. “They went into a toilet and came out 20 minutes later, clothes and hair all over the place,” a source claimed.
