With his taste for the finer things, George Takei was seemingly perfect to lead the men in this week's Celebrity Apprentice challenge.

She's recently gone from blonde to cherry red, and now Aubrey O'Day has gone one step further by dying her dogs' hair, as well.

It seemed to be a Celebrity Apprentice task tailor made for a former racing car driver. So when former Formula One star Michael Andretti decided to step forward and lead a task promoting a new car on this week's edition, he was certainly taking a risk.

Last week’s Celebrity Apprentice ended on a cliffhanger with either Clay Aiken, Arsenio Hall or Aubrey O’Day facing the chop.

Could not believe his luck

The 28-year-old television star opted for a pair of retro-style high waisted bottoms that did nothing to flatter her voluptuous figure.

Managed to pull off odd look

'We wouldn’t have done the "All-Star" concept unless we were able to get the right contestants back,' said Trump, the boardroom boss who will make and break these youngsters' dreams.

She was tweeting words of wisdom last week as she prepared to make a second attempt at Celebrity Apprentice by participating on their All-Star programme. And on Tuesday it looked like Lisa Rinna was well on her way to victory as she got stuck into some work at The Meatball Shop in New York City.

Magician Penn Jillette says there's nothing magical about The Celebrity Apprentice or its creator, Donald Trump, ripping the tycoon who regularly Googles himself and 'desperately' cares what people think about him.

Katherine Webb, who shot to fame after ESPN's cameras panned to her as she cheered on her quarterback boyfriend in the BCS Championship game, let the news slip on Twitter on Thursday.

Maybe they'll have better luck the second time around.

Drama reaches boiling point

Geraldo Rivera, Keshia Knight Pulliam, Brandi Glanville, Kenya Moore, and Kate Gosselin are 'among cast members' in the mix, according to TMZ.

They're both used to dealing with families - although one is a lot bigger than the other.

Brandi Glanville used her supple side to drum up support for her and Kate Gosselin's pie making on Celebrity Apprentice on Tuesday.

Brandi, 41, was spotted showing off her long and lean legs in a revealing LBD as Kate, 39, covered up in a big winter coat on set of the NBC show in New York.
