Celebrity informants report that confirmed four months pregnant Nicole Richie will walk down the aisle with BF/Baby Daddy Joel Madden before she is scheduled to begin serving her four day County Jail term for a second DUI in late September.

“Joel said to Nicole, ‘Let’s get married before you go to jail,’” a source close to the couple tells Star Mag. “She was so happy. He’s doing this so she feels secure behind bars. The last thing he wants is for her to worry about where they’re at while she’s in jail.”

The couple is reportedly planning a September 21st wedding and Nicole will likely do her jai time from September 24-27.

“Nicole wants to get married first, and then serve her time,” the source says. “But she’s way too stressed about jail to plan the wedding, so she’s hiring a wedding planner to coordinate the details.”

“They’ll most likely tie the knot at Joel’s mansion in Glendale, California, although Nicole’s dad, Lionel Richie, has offered his house in Bel-Air if they want to use it. The other, less public option is to head to Madden’s hometown near Annapolis, Maryland. “Joel doesn’t want a circus,” another friend says.

Joel reportedly told Nicole: “We need to get beyond all the bulls —t that is dragging us down and learn to lean on each other.’ That was music to Nicole’s ears - she couldn’t stand the thought of losing him and facing jail.”

“He really hadn’t had time to process it all. The prospect of becoming a father was a pretty heavy hammer on him,” the friend says.

Snitches claim: “But seeing how scared Nicole was about going to court brought out his protective streak. Hew wanted to give her something to hang onto. There are a lot of times I thought he would throw in the towel with her, but the truth is, he really does love her.”
