Britney Spears was left embarrassed on Sunday (13Jul14) after forgetting to pay a restaurant bill following a mix-up with her security guard. The Toxic hitmaker enjoyed a light lunch with her boyfriend David Lucado at The Cheesecake Factory in Thousand Oaks, California and told her waitress the $30 (£18) bill would be picked up by her bodyguard. She and Lucado then left the eatery, but her guard assumed the meal had been paid for and did not return to hand over the cash. Spears was later made aware of the mix up and has since settled her debt with the restaurant. Her representative tells TMZ.com the singer feels "horrible" about what she insists was an honest mistake.
