Although Christina Aguilera may be keeping a stiff upper lip about her impending divorce from husband Jordan Bratman, insiders are spilling the beans about possible spousal abuse that the "Beautiful" singer suffered at the hands of her jealous hubby. Radaronline.com is reporting that the 29-year-old showed up at the ER in the middle of the night just a few days before calling it quits with her baby daddy. The source who spotted the famous singer at Cedars-Sinai says that it appeared someone had given the blonde bombshell some serious lip disservice. The insider tells Radaronline.com, "Christina was bleeding from her mouth and had a bit of a busted lip. Jordan told the nurses she had fallen down." The source adds that she also had some suspicious bumps and bruises on her. According to the spy, Aguilera's private surgeon showed up to stitch up her lip. Radaronline.com is reporting that the very day Aguilera went public about her split with Bratman -- the divorce, that is -- she was snapped wearing a hat over her face with a small cut below her lip. The couple claimed irreconcilable differences, but Radar maintains that the couple had an open marriage. An insider suspects that Bratman may have tired of his wife's swinging ways. Says the source, "My understanding was that Jordan wasn't involved when she [Christina] brought girls home, so maybe the divorce is because Jordan's jealousy got the best of him." According to Radaronline.com, Aguilera's people had no comment. The songstress has been spending plenty of time with Lindsay Lohan's ex Samantha Ronson. Aguilera has admitted to Redbook that the break-up has taken its toll on her. She says, "It's not easy, and there have been a lot of tears and sadness. It's impossible to redefine yourself and your life overnight. Thankfully, I have my mom and a small group of close friends who are there for me 24/7 and whom I can trust and depend on. On days when it feels impossible to even get out of bed, much less function as a mother, their support and encouragement have kept me moving forward."
