Bobby Flay allegedly had an affair — and a baby — with a Mad Men star

Bobby Flay and Stephanie March’s contentious divorce got even angrier today when it was revealed he could be January Jones‘ baby daddy.

The celebrity chef’s now-ex-wife became extremely suspicious that he had an affair with the Mad Men star after it was revealed she called him in the aftermath of Jones’ 2010 DUI accident. Jones and Flay had both been drinking at The London West Hollywood Hotel earlier in the evening.

After the incident, Flay denied he and Jones were anything more than passing acquaintances.

“I know Stephanie basically asked him after January Jones, ‘Did you f*** her?‘” an insider told the New York Daily News‘ Confidenti@l. “He told her no.”

But it doesn’t sound like March is buying it. A source told In Touch, “Stephanie is claiming in court papers that Bobby committed adultery with January several times during the early months of 2010. She says they had sex many times and in different places, including the London hotel in Los Angeles.

“They had a huge fight over January shortly before Stephanie asked him to move out of their place,” the source continued. “There is communication between Bobby and January that indicates they were more than acquaintances.”

Jones gave birth to her son Xander in September 2011 and has never named his father. Could it be Flay?

Regardless, March says she has ample evidence that Flay had multiple affairs in addition to Jones, including with his personal assistant and a food stylist, and wants their prenup nullified.

“This fight is far from over,” the insider said. “Stephanie only wants what is fair, but she’s prepared to do what she needs to get it. She has proof of affairs.”
