Aiken was critical of Takei's turn as project manager in last Sunday's living window task, eventually blaming the Star Trek actor for Team Unanimous's loss in the boardroom.

Takei - who was ultimately fired by Donald Trump – has now accused Aiken of "backbiting" in order to get ahead in the competition.
"I pegged him immediately as the catty one, despite that molasses sweet accent," Takei told Zap2it. "He is determined to win, and he will do it with little snide snipes."
Takei also singled out three of his former competitors as top contenders to become the next Celebrity Apprentice.
"Penn [Jillette] is the one. Arsenio [Hall] is a smart savvy guy, and he would be a good candidate as well," he revealed. "And I love Lisa [Lampanelli]."
Takei joked earlier in the week that he's sad he "did not live long and prosper" on the reality series.
The Celebrity Apprentice airs on Sunday at 9/8c on NBC.
