Women Who Work: Rewriting the Rules of Success will advocate for an 'inclusive and celebratory' vision for working women

The 34-year-old took to her eponymous website and Instagram page on Monday to reveal in a playful video that she has written a second book

Ivanka Trump may have only given birth to her third child two months ago, but she is already joking about having another baby on the way — her new book.

The 34-year-old mom took to her website and Instagram page on Monday to reveal she had some 'amazing news' to share with her fans before she held up a cardboard cutout featuring the number four. And while Ivanka announced her third pregnancy in a similar fashion last September, she couldn't keep up the misleading ruse for long.

'Okay, so I am not pregnant with baby number four,' she admitted in the clip. 'But I do have another very exciting project in the works, and it is also a labor of love. It is a book called Women Who Work.'

Ivanka, who published The Trump Card: Playing to Win in Work and Life in 2009, went on to say that her second book is slated to come out in the spring of 2017.

The executive vice president of the Trump Organization noted that she launched her eponymous lifestyle website two years ago because she was 'really convinced that we needed to change the dialogue around women and work'.

'Every day we are seeking to inspire and empower this next generation of women and there is nothing more powerful than that,' she added.

Portfolio, a business imprint of Penguin Random House, told the Associated Press on Monday that Women Who Work: Rewriting the Rules of Success will advocate for an 'inclusive and celebratory' vision for working women and help them 'create the lives they want to live'.

'Today's generation of working women is the first to be able to unabashedly embrace the fact that our lives are multidimensional,' Ivanka said in a statement.

'We're deeply invested in our careers, but they don't solely define us. For us, it's about working smarter, not harder; integrating our personal passions and priorities with our professional goals in order to architect lives we love.'

And while Ivanka undoubtedly couldn't wait to share her news, she spent the weekend sharing photos and videos of her darling children on Instagram.

On Sunday evening the proud mom posted a video of her four-year-old daughter Arabella playing the Twinkle, Twinkle, Little Star on the piano.

'Piano practice!' she captioned the image, which sees the little girl playing inside the family's Park Avenue apartment. Arabella's hair is pulled back in a French braid as she focuses on the music notes in front of her.

Earlier in the day, she posted a picture of two-month-old Theo swaddled in a white blanket In the caption for the photo, showing the tiny tyke snoozing away, Ivanka simply wrote a series of 'Zzz's.

It's just the latest in the masses of family-focused photos that are all over the entrepreneur's Instagram page.

Just last week, Ivanka shared a heartwarming family moments from New York's Central Park, where she frolicked in the sun with her four-year-old daughter Arabella.

Happy days: The 34-year-old also enjoyed some family time earlier this week with a picnic in Central Park, as she showed with a photo of herself cuddling four-year-old daughter Arabella

The photo shows Ivanka in a black and white dress hugging her little girl, in a pair of pinkish orange pants and a matching headband, surrounded by a pair of stripey hula hoops.

The photo was likely taken last Tuesday, the same day that Ivanka appeared alongside her father Donald Trump, 69, at Trump Tower, looking somber with her older brother Donald Trump Jr.

The executive vice president of the Trump Organization has been tirelessly campaigning for her father since he announced his presidential bid last June, and Tuesday was no exception.

Ivanka donned a classic white and black patterned dress to the event, and though she looked lovely, her mind may have been back with her little boy.

The businesswoman appeared slightly preoccupied as she took to the stage with her family to show support for The Donald after the long holiday weekend.

Earlier that morning, she shared a photo of herself giving Theo a kiss on the cheek as she holds him in what appears to be his nursery — just hours before she appeared at her father Donald's press conference at Trump Tower regarding his donations for veterans.

'This boy is pure sunshine,' she captioned the precious image, which sees baby Theo looking over his adoring mother's shoulder and staring at the camera.

In the candid snapshot, Theodore is still in his footed onesie, while Ivanka is dressed casually in a brown hooded athletic top, leaving her blond hair pulled back in loose braid topped with a black headband.

Although he is only two months old, Theo's bedroom is also already filled with children's books, stuffed animals, and framed photos of him posed with his father James Kushner, 35, and his siblings, Arabella and two-year-old Joseph.
