Icon winner Janet Jackson won’t need any additional star power when she makes her first TV performance in nine years.

Over there

Viewers still suffering from Obama withdrawal will get their fix with the documentary “The Final Year,” which looks at peace efforts just before the changing of the guard.

A deal for you

The next time the “Absolutely Fabulous” gals throw a cocktail party, they’ll want to put Victoria Sandringham on the invite list. She’s the discount-furniture queen who successfully sells “Sando” as one of the summer’s must outrageous comedies. As played by Sacha Horler, Victoria halfheartedly tries to pitch her way back into the family after sleeping with her daughter’s boyfriend and treating the rest of the clan like mere extras in one of her TV commercials. Fans of Patsy and Edina — or “Arrested Development” — will be delighted by this Australian gem.
