On Sunday's episode of the Celebrity Apprentice, the overwhelmed pop star, 28, headed to the elevators, normally reserved for contestants given the boot by Donald Trump--leading many to believe she was throwing in the Celeb Apprentice towel.

"I don't want to be around all the negativity anymore," O'Day confessed. "The environment is so ugly. I just don't know if this is the right place for me."

Rest assured, Danity Kane fans: O'Day explained all on Twitter Sunday. "I stay!" she tweeted. Turns out she just needed a break from the stressful boardroom environment. "lol. I went 2 church!" she shared.

O'Day seemed to be in much better spirits April 1 in general, when she took to Twitter again to play an April Fool's joke on her followers.

"I've been nervous to tell you this tweets, it's been 3 1/2 months in hiding" she wrote. "But, I'm PREGNANT."
