Former Hills star Kristin Cavallari has been telling friends that giving birth to son Camden "hurt like a bitch and felt like period cramps, but 10 times worse," a source tells Us Weekly in the new issue, on stands Friday.

Cavallari, 25, welcomed her first child with fiance Jay Cutler, the 29-year-old quarterback for the Chicago Bears, at 2 a.m. on August 8.

Despite the agony and the fact that doctors were forced to break her water, "Kristin says she would do it all over again."

For now, the new mom is focused on losing the last of the 25 pounds she gained while pregnant, adds the insider.

"She still has some weight to go on her stomach, but she is almost back!"
