Ivanka Trump finally broke her silence about rumours she might fill the role of first lady when her father takes office on Friday in an interview with Good Morning America.
"Well, I think its an inappropriate observation. There's one first lady and she'll do remarkable things," said Ivanka, referring to her father's wife Melania.
She later told Deborah Roberts in the interview, which will air in full on 20/20 in the US next Thursday, that she also found the comments "sexist", saying that they seemed to suggest that two women could not have a powerful role in her father's White House administration.
Ivanka also revealed during the interview that she is still close to former first daughter Chelsea Clinton despite her father's victory over Hillary in the election, and said that she will likely go to her for advice once she settles down in Washington DC next week.
Meanwhile, CNN reports that Melania is starting to put together the Office of the First Lady and is considering a male for the role of social secretary.
The individual is not part of Melania's New York social circle according to the report.
A source also said Melania's top priority will be to "make the house a home for her family" once she becomes first lady.
Ivanka, who wore a $2490 Carolina Herrera dress for the interview, also spoke about how difficult it was to step down from her role as an EVP in the Trump Organisation while also backing away from her leadership role in her eponymous clothing and accessories line.
"It's emotional that I'm stepping away from my business," said Ivanka, who then pointed out, however, that the reward was much greater in the end.
"My father will be president and hopefully I can be there to support him and to support those causes I have cared about my whole professional career."
Ivanka spent her last day in her New York office on Wednesday, and uploaded a photo to her Instagram as she said goodbye to her job in the Big Apple to head to the nation's capital.
"My last day in the new @ivankatrumphq space. I'm a little jealous I won't be here to enjoy the beautiful new office with my talented team," wrote Ivanka.
Last week, Ivanka attended a women's power dinner ahead of her big move, which was held at her good friend Wendi Deng's $34m penthouse apartment.
Among the guests who turned up to give Ivanka advice were Tory Burch, Mika Brzezinski, Tina Brown, Christy Turlington Burns, and former White House press secretary Dana Perino.
Pattie Sellers, the executive director of Fortune's Most Powerful Women Summit, was another guest at the dinner, and wrote about the evening for Fortune.
"Trump explained that she wanted to learn from the efforts of leaders in their fields," said Sellers.
"We talked about entrepreneurship, equal pay, paid leave, and a lot about where the Donald Trump Administration may have the most opportunity: education."
Also on hand Thursday night was Goldman Sachs executive Dina Powell, who the Trump team announced earlier that same day would be joining the administration in a senior role focused on entrepreneurship, economic growth and the empowerment of women.
It is expected that Ivanka will work closely with Powell once her father is in the White House.
Powell put the dinner together on Thursday, and was in charge of coming up with the guest list for the event.
Glamour editor-in-chief Cindi Leive, Time managing editor Nancy Gibbs, IBM CEO Ginni Rometty, Deloitte CEO Cathy Engelbert, and Xerox chairwoman Ursula Burns also attended the event.
The group was not entirely female either, with Ford Foundation president Darren Walker and National Urban League CEO Marc Morial on hand as well for the invite-only dinner.
Ivanka has yet to officially reveal what her plans are once her father takes office, but did say last Wednesday that her first priority once she moved would be to settle her family into their new residence while her husband Jared Kushner begins his new job as a senior advisor to her father, for which he will not be paid.
She has already busied herself working behind the scenes by phoning members of Congress in an attempt to rally support for childcare proposals, including tax-free childcare accounts and childcare deductions for families making under $500,000 a year.
Ivanka reportedly told the women at the dinner on Thursday that this effort was a priority for her father once he enters office this week.
Ivanka will certainly be the most visible first daughter that has ever been in the White House, and a source close to the family told DailyMail.com that she was taking the role "very seriously''.
"She want to be respectful," added the source.
There have been numerous indications over the past few weeks that Ivanka would be taking a role in the White House.
The most notable was the news that the family would be moving into a $5.5 million home in the District's Kalorama neighborhood.
One week later, Trump announced that Ivanka's husband Jared Kushner would be joining his staff as a senior advisor.
It is unclear however if the couple bought the six-bedroom residence or will just be renting the home, which was sold just before the holidays to an unknown buyer.
The Trump-Kushners will now be just two blocks away from the home of Barack and Michelle Obama, who are moving to the neighbourhood after next week so that their younger daughter Sasha can finish high school in the city.
