“The Celebrity Apprentice” (9 p.m., NBC): They come armed with star power (however dimming), bravado and a favorite charity. They aim to put it all to work as “The Celebrity Apprentice” premieres with its all-star celebrity lineup of candidates. On this new twist on the “Apprentice,” now in its seventh season, the 14 contenders will be competing in business-oriented tasks around New York to raise money for their pet charities, with the final winner being crowned “Celebrity Apprentice” and delivering a $250,000 bonus check to his or her favorite cause. As usual, the tasks will be judged in the boardroom by Trump and his advisers, who include Trump’s children (and colleagues) Ivanka and Donald Trump Jr., alongside Trump Organization veteran George Ross. The celebrity contestants include: country music star Trace Adkins, model-actress Carol Alt, actor-writer Stephen Baldwin, Olympic gold-medalist Nadia Comaneci, former Playboy Playmate of the Year Tiffany Fallon, Olympic gold medalist Jennie Finch and media magnate Nely Galan. Also, actress-writer Marilu Henner, heavyweight boxing champ Lennox Lewis, former “Apprentice” star Omarosa, TV personality-writer Piers Morgan, Ultimate Fighting Champion Tito Ortiz, former “Sopranos” regular Vincent Pastore, and rock star-personality Gene Simmons.

“ER” (10:01 p.m., NBC): A face from the past resurfaces on “ER” as original cast member Gloria Reuben reprises the role of Jeanie Boulet for one episode. A frazzled Jeanie finds herself back in the ER after her son Carlos takes a nasty fall during gym class.
