Omarosa Manigault Newman, one of US President Donald Trump's most vocal black supporters, is to quit.
A White House spokeswoman said Manigault Newman was quitting the Office of Public Liaison to "pursue other opportunities".
"We wish her the best in future endeavours," said press secretary Sarah Sanders.
Manigault Newman was often referred to by viewers as the "villain" on Trump's reality TV show the Apprentice.
Sanders added that Manigault Newman would depart on 20 January, one year after Trump took office.
She was fired by White House Chief of Staff John Kelly, and escorted out of the building after a vulgar tirade, according to White House correspondent April Ryan.
Critics said Manigault Newman's role at the White House was vague and ill-defined, and that she seemed to spend more time planning her wedding than organising outreach.
During her tenure, she attracted controversy when she brought a 39-person wedding party to the White House for an impromptu photo shoot, according to Politico.
Over the summer, she caused uproar at an event for black journalists, when she paced on stage while arguing with the panel's moderator and refused to discuss her boss, President Trump.
In a 2004 interview with Playboy, Trump described her as a liar.
He said he would not offer her a job reference, except if she was appearing on a soap opera.
But following his election to the White House, he appointed her to the Office of Public Liaison earning a reported $179,700 ($134,000) a year.
This was not her first time working for a presidential administration.
After graduating from Washington DC's historically black Howard University, she worked for Vice-President Al Gore, before joining President Bill Clinton's personnel office, then the US Commerce Department.
She wrote a 2008 book The Bitch Switch, which was billed as "a step-by-step guide for locating your inner BITCH, personalising your switch, and knowing when to turn it on and when to turn it off".
In her book, Manigault Newman described her government supervisor as someone who "constantly sabotaged her efforts".
But a former Clinton official told People magazine Manigault Newman "was asked to leave as quickly as possible" and one member of staff "wanted to slug her".
