American Idol (8pm, Fox) - Neil Patrick Harris and Joe Jonas are the guest judges tonight on "American Idol." NPH could finally be the key to getting me to watch this show.

State of the Union (9pm) - The State of the Union address is airing on all major networks and all cable news networks.

Living with Ed (9pm, Planet Green) - In this episode of Ed Begley's entertaining reality show about his "super green" lifestyle, Ed visits a town in Oregon which is "off the grid" and then wants to move his family there.

Psych (10pm, USA) - "Psych" opens season four in a brand new time slot. The show has always enjoyed a Fridays at 10pm home, but with its partner "Monk" out to pasture, USA is shaking things up a bit by moving it to a presumably more ratings-friendly night of the week. The premiere episode features guest star John Cena. (First we had Stone Cold Steve Austin on "Chuck," and now Cena is on "Psych?" Well, wrestlers are by definition pretty good actors.) Tonight, Shawn thinks a soldier's suicide was really murder, and believes Juliet's mercenary brother (played by Cena) is involved. 

Also on tonight: Florida State at Duke (9pm, ESPN), Melanie Griffith guest stars on "Nip/Tuck" (10pm, FX), "Being Erica" is back (10pm, Soapnet), and "Leverage" is also on (10pm, TNT). 

You've probably seen Ed Begley Jr. as an actor, most famously on the 1982 hospital drama "St. Elsewhere," and more recently as the doctor (again!) brother-in-law on Lifetime's "Georgia O'Keeffe."

But these days Begley might be better known as the greenest man in Hollywood.

And exploring his eco-friendly side is the premise of his reality show on Planet Green's "Living with Ed"; the new season begins tonight at 9. (Planet Green is channel 115.)

Environmentalism, of course, concerns all ethnic and cultural groups. And elements of the green movement -- from electric cars to organic foods -- should too.

That's the impetus behind TV One's new show "Mario's Green House," premiering today at 6 p.m., a half-hour reality show about actor/director Mario Van Peebles and his family going green.

Well, it's not really a reality show; the press release later describes it as an environmental 'how to' and family comedy, and that's closer to the truth. Every part of it seems scripted. But that's OK.

Although familiar with some of Georgia O'Keeffe's work, I don't really know much about her life.

I can't say after watching Lifetime's "Georgia O'Keeffe," (Saturday, 9 p.m.) I learned a lot more.

But it's probably not fair to expect that; this is a Lifetime movie after all. So, this portrait of the artist is told through the story of her tortured love affair with photographer Alfred Stieglitz.

Luckily, O'Keeffe is played by Joan Allen and Stieglitz is played by Jeremy Irons. Which means the acting is terrific.
