Model AMANDA PAGEL was outraged when she discovered the charming Brit she was dating was sleeping with Britney Spears. The Wyoming native has spoken out about her brief romance with the Toxic troublemaker's on/off photographer beau Adnan Ghalib, revealing she had no idea the snapper was still dating Spears behind her back. And, to make matters worse, the married paparazzo used the same pet name for both his girls. Pagel, 21, tells the upcoming issue of America's In Touch magazine that Ghalib swore his relationship with his ex was purely platonic. She tells the publication, "The first time he came over to my house, I asked about Britney. He swore they were just good friends. "He promised they weren't having sex and he kept reminding me what a hard time Britney had been through." Pagel admits she fell for the paparazzo after meeting him at a party in January (08), and she was charmed by his "gentle and sweet" nature. She adds, "I felt like I'd known him all my life. He's a fantastic kisser, too." But the romance quickly soured when Pagel learned the cute nickname Ghalib gave her was the same he used when cooing about his 'ex' Britney. She explains, "He started calling me Bebe but I found out that's his pet name for Britney, too, which hurts."
