The past week has been a roller coaster of celebrity splits. Here's a rundown of which celebrity parents surprisingly broke up:

Courtney Cox and David Arquette, who are parents to 6-year-old Coco, revealed early this week that they separated months ago. As days went by stories of infidelity started to emerge. To dispel rumors, David called up his long-time friend Howard Stern to set the record straight. What he shared was more than most wanted to know including that he hadn't had what he termed "methodical" sex with his wife in four months and that she "didn’t want to be his mother anymore." The next day he publicly apologized, although sources told People that nothing he said would surprise Courtney.

While the celebrity world was reeling over the Cox-Arquette split, another celebrity had bad news to deliver: Christina Aguilera. Christina has been with her husband, Jordan Bratman since 2002, and they are parents to 3-year-old son Max. Sources say that they’ve been separated for months and had become more friends than lovers at this point.

The celebrity break-up that started the week of splits was between Laura Dern and husband-musician Ben Harper. The couple has two children, a 9-year-old son and 5-year-old daughter. Laura Dern seems to have a history with sudden breakups (see Angelina Jolie meets Billy Bob Thornton for one) and it sounds like this was no different. Reportedly, the papers she was served that cited “irreconcilable difficulties” were out of the blue and Ben Harper has denied any spousal support to be awarded.
