I am an only child, so I have no clue about the sturm und drang of siblings.

But the Sunday night finale (as it turned out) of Kisha and Jen, the sistah sisters on reality TV show “Amazing Race” was a pisser – literally. Blame it on cry baby Kisha, who’s been playing the drama card since last week when challenged to swim 400 meters. She cried through that, which put them in last place.

They were saved by the fact that the pit stop wasn’t the end of the challenge and lived to take the second half that involved deciphering Chinese dialect and eating strange fruit. Kisha washed down the eels and tempura starfish with water – lots of it. By the time they made it to the final location, they were neck-and-neck with the cheerleaders from hell for a shot at last place or as one of the final three teams who will go on to compete for $1 million.

So what does L’il Keesh do? Hit the port-a-potty. No joke. With everything hanging in the balance, she does the unthinkable and they reach host Phil a split second too late.

Remember that stalker astronaut who drove across three states wearing Depends? It’s all about focus.

What the frizzle! Donald Trump fired T-Boz!!? Celebrity Apprentice, where reality TV meets bidness school, is, ultimately, a platform from which The Donald can club the self-esteem of team members he’s reduced to minions. The Apprentice franchise started off pitting sharp, serious MBAs against one another for a shot at $1 million and a chance to work within Trump’s empire. It quickly devolved into the celebrity schtick, which largely involves the likes of Dennis Rodman and Joan Rivers hitting up their friends for bank in order for their team to make the most money.

T-Boz did her team proud last week when she acted as Project Manager, handing out orders and assignments like she was born to CEO. This week, however, she headed back into the board room with Project Manager Melissa Rivers, who asked for volunteers. The fact that she put herself in a position to be axed infuriated Trump who sent her packing, yelling after her, “Never volunteer!!”

Almost as ruthless as her tangle with former TLC management.

Mrs. Shawn Carter keeps a crazy schedule, so we like to see her mix it up with a little playtime on the clock. Nintendo has just launched it’s newest title, Rhythm Heaven with Ms. B showing her newbie gaming skills on the pocket DST system. Check her wrist action:

Reuters reports that Isaiah Washington is taking on the role of singer Lou Rawls in the bio-pic, “Through The Eyes of A Son.” Pathway Entertainment has acquired the script, described as an “uncensored take on the singer” written by his son, Lou Rawls, Jr.

Washington will next be seen in “Hurricane Season,” the story of the fate of a New Orleans basketball team after Hurricane Katrina.

Jada Pinkett Smith is downsizing. The actor/producer/director/rocker is set to star in “Time Heals,” an original series set to air on the TNT network. Variety reports that Pinkett Smith takes on the role of a “strong but caring” director of nursing in a Charlotte, N.C. hospital. Couple of things:

-would love to see them switch it up and bring back those old school nursing whites (the uniforms, of course) – the kind with the lace-up rubber soled shoes and perky little starched hats.

-North Carolina? Seems like a random locale. Either they’re hoping for the southern accents to add another layer of intrigue, or they got some really great tax incentives to shoot there.

-another television hospital drama. How on earth will they make it original? Then again, who says they’re trying to?

When Variety first reported on Halle Berry’s latest project, we had a WTF moment, but chose to reserve judgement. This is, after all, Halle Berry. Still, the premise behind Frankie and Anne stinks.

Berry, who produces as well, plays a schizophrenic woman battling between “who she is and a racist Caucasian personality that preys upon her mind.” Production had not yet started when the project was first announced back in April, but the production pic sent in by Sergio brings us back full circle.

WTF, Halle??

How many more busted projects will it take before producers get the message that the Middle East in headlines means no tickets at the multiplex? Still much too embroiled in the topic, American audiences are ignoring movies like the recent Jordanian thriller, Body of Lies for much much lighter fare.

Jossip reports Beverly Hills Chihuahua topped weekend box office take for a second weekend, raking in a reported $17.5 million. On average, the war films released since last December have grossed around $70,000 – and that’s probably concessions.

Aussie website, LiveNews reports that a certain unnamed Hollywood exec almost pulled the plug on Australian director Rowan Woods because Woods fought to keep Oscar winner Forest Whitaker in his new film Winged Creatures, a story that centers around a random shooting in a Los Angeles diner and how it affects the lives of those who witness it. The executive is said to have dismissed the actor as “ugly, black and unbankable.”

Despite having a cast which included Guy Pearce, Kate Beckinsale, Dakota Fanning, Jeanne Tripplehorn and Jennifer Hudson, Woods said the company who owned the script couldn’t accept Whitaker as a leading man. Woods told a gathering of colleagues at the recent Australian Directors Guild conference that the company, which he wouldn’t name for legal reasons, eventually let go of the script because of their disagreement over Whitaker. The executives wanted a Michael Douglas or an Al Pacino considered for the role.

“They wanted everyone but Forest Whitaker,” Woods told the audience, “… and this is one of the best actors on the planet.”

Producer Lee Daniels was so impressed with Mariah Carey’s work ethic on his upcoming flick, Tennessee, he cast her in another! Tennessee, which debuted at the Tribeca Film Festival, tells the story of two brothers who travel from New Mexico to find their estranged father. Carey plays a battered wife who meets up with the two running from her state trooper husband.

Describing his experience with the notorious diva on the set as “a party from beginning to end,” Daniels subsequently cast her in Push as a Harlem social worker who takes to her new client, an obese, HIV-positive woman twice impregnated by her father. Alrighty, then.

In a wide-ranging interview with CNN’s Soledad O’Brien at the station’s convention headquarters, The CNN Grille, Spike Lee made a producer’s request: He asked O’Brien and CNN to do a “compare and contrast” between the Democratic convention and the Twin-Cities pow-wow of the GOP.

“Look at the composition — at the faces, the genders, the racial composition.”

Leave it to Spike to provide color commentary. He’s right, though: a picture is worth 1,000 votes, uh, I mean, words.
