Nicole Richie is admitting her guilt over her second DUI and will serve jail time since it was her second conviction.

Sources tell TMZ Richie will plead either guilty or no contest to DUI. She will appear before the Court Commissioner, who will sentence her on the spot. Sources say Richie will receive a minimum sentence of five days in jail. By law, anyone with two DUI convictions must serve at least five days. This conviction will be Nicole’s second DUI.

Richie appears to want to put the arrest behind her so she can focus on her pregnancy.  She and boyfriend Joel Madden are expecting their first child together.
