NBC has committed to a comedy produced by Ellen DeGeneres and starring her wife Portia de Rossi, Nikki Finke's Deadline Hollywood reported.

All four major broadcast networks reportedly vied for the comedy from Warner Bros TV and DeGeneres' nascent production company A Very Good Production.

The unnamed comedy will be about dueling sisters, one of whom will be played by de Rossi. DeGeneres will executive produce.

De Rossi, 38, is best know for playing lawyer Nelle Porter on Ally McBeal and inept activist Lindsay Bluth Funke on Arrested Development. Both shows were early successes for Fox. She also played Olivia Lord on the FX medical drama Nip/Tuck.

DeGeneres, 53, and de Rossi married in California in 2008. The couple was among the 18,000 who married during the period of time after the California Supreme Court legalized gay marriage but before Proposition 8 overruled the court's ruling. De Rossi, born Amanda Lee Rogers, changed her name to Portia Lee James DeGeneres last year, but is known professionally as Portia de Rossi.

The series will be written by Samantha Who? co-creator/executive producer Don Todd.
