Britney Spears' bodyguard Daimon Shippen allegedly used to sell sex toys on the internet, according to a gossip website.The 34-year-old burly security guard - who has been protecting Britney and helping her look after her children - was reportedly fired from his previous agency, Galahad Security, because of his adult website business.The domestic service security agency he now works for reportedly does not perform regular background checks. Sources also say Daimon is gay and currently has a boyfriend called Sam. Britney, 25, has denied rumors she and Daimon are dating after they were spotted sharing a candlelit dinner in the Windows Lounge of Los Angeles Four Seasons hotel earlier this month, after which he spent the night at her home. A source said: "He's her bodyguard and manny. They're not dating. Daimon is funny, but on the quiet side. He is tickled by all the attention, but he really wants to focus on his job. He just wants to take care of Britney and her kids."The bodyguard also accompanied the singer - who has two sons, 22-month-old Sean Preston and 10-month-old Jayden James, with her estranged husband Kevin Federline - to church.Britney carried sleeping Jayden while Daimon carried Sean and comforted him when he started crying.A source explained: "Britney doesn't have a nanny. When the kids are with her she takes care of them and she is a very hands-on mom. Daimon also sometimes helps her out. She really would like to have them for more time than she does but she is willing to live with the agreement with Kevin that she has now."
