Food Network star Bobby Flay and former "Law and Order: SVU" star Stephanie March's divorce proceedings are heating up, as the celebrity chef has been accused of adultery with "Mad Men's" January Jones by his soon to be ex-wife.

Flay and March split in early April after 10 years of marriage.

Reportedly March is challenging the prenup on the grounds that Flay allegedly cheated on her with three women, including actress "Mad Men" actress January Jones. In the prenuptial agreement, Flay is required to pay the actress $5,000 a month.

The former "Law & Order: SVU" star claimed in court papers that the 50-year-old celebrity chef "committed adultery" with Jones several times in early 2010, as reported by In Touch.

The magazine also revealed that March accused Flay of cheating on two separate occasions with a food stylist and his assistant.

"Stephanie claims 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," a source revealed to In Touch.

The Daily News reported that Flay came to Jones' aid after the actress crashed her car. The star of "Beat Bobby Flay" stated at the time that they had watched a basketball game together at the London hotel the previous evening. Flay remarked the actress has asked for his number because she wanted his advice on redoing her kitchen.

Despite the issues that have led to their tempestuous divorce, the duo's marriage was plagued with problems. Said a source to The Daily News, "He [Flay] travels a lot. He always has. It's not a typical marriage. It really is a celebrity marriage. I don't think she gets on a plane and goes everywhere with him."

According to Page Six, Flay and March's prenup has no infidelity clause, meaning it's not affected either way if one or both parties had an affair..
