Newly single actor-singer Nick Lachey is developing a WB Network sitcom in which he would play a famous baseball player trying to navigate a new marriage.

The untitled project will be crafted by Danny Jacobson, the co-creator and executive producer of "Mad About You," who described it as a "romantic comedy under a microscope."

Lachey, the former star of MTV's "Newlyweds" is no stranger to the WB, having logged multiple guest shots last season on the network's drama series "Charmed." He and wife Jessica Simpson last Wednesday announced their separation after weeks of speculation about their closely watched marriage.

In January, Lachey signed a solo deal with Jive, but the status of his next album is unknown.
