E! has greenlighted another reality series for its 2005 slate, this time following a jet-set mother and daughter duo who seem like the “Gilmore Girls” crossed with Paris Hilton. Lisa and Brittny Gastineau are the pampered ex-wife and daughter of former NFL player Mark Gastineau. In “Gastineau Girls,” the duo search for romance in New York’s society scene. The half-hour weekly series, produced by True Entertainment, will premiere Feb. 1.
