Celebrity chef Jenn Louis has been arrested on suspicion of attacking her husband at their popular North Portland restaurant Lincoln.

Police showed up at the restaurant at 3808 N. Williams Ave. about 9:15 p.m. Friday following a 911 call by Louis' husband, David Welch. He told police that she had socked him in the nose and then left, according to Sgt. Pete Simpson, Portland police spokesman. When officers arrived, they interviewed Welch and took Louis' statement outside the restaurant.

Based on their accounts, Louis was booked into Multnomah County jail just before 11 p.m. on a domestic violence misdemeanor assault. She was released without bail.

Welch told The Oregonian/OregonLive that he finished his shift at Lincoln on Friday but only worked a half a shift on Saturday because of how he looked. He confirmed that Louis punched him in the nose.

"I'm fine," he said. "I'm not injured further than that."

He said the story was trivial but declined to provide details. He would not say whether he is pressing charges. The two are in the process of getting a divorce, he said. They've been married for 12 years.

A photo on the Lincoln website depicts happier times with Welch beaming with a big grin as Louis plants a kiss on his cheek.

Welch said he's not worried about any fallout on the restaurant. "We're going to do the best we can to serve the best produce and continue to focus on customer service," he said.

Louis did not work at the restaurant on Saturday and did not respond to an email seeking comment.

Louis, 44, and Welch, 42, opened Lincoln in 2008 and then three years later opened Sunshine Tavern in Southeast Portland. Later this year, she plans to open an Israeli restaurant in Los Angeles.

Louis, who attended the Western Culinary Institute in Portland, has been a rising star. She launched her career in Portland as a line cook at Wildwood, then started a catering company. Lincoln was a big hit soon after it opened, landing on Conde Nast Traveler's "Hot List" of the best 50 new restaurants in North America. It was ranked 28 last year among 101 restaurants in The Oregonian/OregonLive's edition of Diner.

In 2012, Louis was named a best new chef by Food & Wine Magazine. She also appeared on Top Chef Masters in 2013 but was eliminated. Last year she published her first cookbook, "Pasta by Hand."
