Nicole Richie Shuns Hospitalized Mom

Nicole Richie may have mended fences with her one-time nemesis Paris Hilton, but the tiny reality TV "star" faces another personal problem.

For once, we're not talking about the fact that she doesn't eat.

Nicole Richie has reportedly shunned her mother, Brenda Harvey-Richie, even as she remains in the hospital after major surgery.

"Brenda was in the hospital. She had a hysterectomy," said a source.

"Nicole hasn't visited her since."

In other mom-daughter news, a similar spat meant Britney Spears reportedly didn't visit her hospitalized mother, Lynne, on Mother's Day.

Richie, who is not back in rehab as some sites reported, has been making regular visits to her therapist, and insiders say her issues with her mom may be to blame:

"The two have not been getting along lately."

Richie's rep had no comment on the feud, which makes the Rosie O'Donnell - Elisabeth Hasselbeck rift seem downright cordial.
