New York, January 7 : Jessica Simpson has contributed her recipes in the 2008 Cowboys Family Cookbook, presented by the wives of the Dallas Cowboys.

The singer is, however, yet to be engaged to Cowboys quarterback beau, Tony Romo.

However, according to Happy Hills Farm Academy/Home founder Ed Shipman, the term ‘wife’ is not taken in a literal sense, rather as a general better half.

"We just work with whomever they''''re currently living with,” the New York Daily News quoted him as saying.

There''''s probably a third of the women that are in there that are considered significant others,” he added.

Amongst the actress’ contribution features recipe for “banana breakfast fruit smoothie" and "no-fat broccoli and cherry tomatoes." (ANI)
