Donald Trump's daughter Tiffany engaged to billionaire Michael Boulos.

Donald Trump 's youngest daughter Tiffany Trump has announced her engagement. The 27-year-old said "Yes" when her 23-year-old billionaire boyfriend Michael Boulos popped the all-important question. Tiffany rushed to Instagram - just one of the many social media platforms her dad Donald is blocked from using - to announce the exciting news.

Gushing over her new fiancé, Tiffany admitted it was an "honour" to "celebrate many milestones" at the White House during her dad's presidency, the most significant of which being her engagement.

"It has been an honour to celebrate many milestones, historic occasions and create memories with my family here at the White House, none more special than my engagement to my amazing fiancé Michael," she penned.

“Feeling blessed and excited for the next chapter," she added.

Alongside the sweet note, Tiffany shared a snap of the loved up pair posing outside the White House.

"Love you honey," her soon-to-be husband wrote in the comments section.

Tiffany was spied flashing her huge diamond engagement ring in the snap, while she put her other arm around her man.

Meanwhile Michael opted for an American flag pin showing support for his fiancée's home country. The pair first struck up a romance in the summer of 2018 after meeting in Mykonos, Greece. Michael, who is the heir to the multi-billion dollar Nigerian conglomerate Boulos Enterprises, was born in Lebanon and grew up in Nigeria before moving to the US after striking up a romance with Tiffany.

After Tiffany announced the news of their engagement on social media, Michael took to his own Instagram page to post the same sweet snap to his followers.

"Got engaged to the love of my life! Looking forward to our next chapter together," he wrote alongside the snap.

Tiffany and her siblings are currently packing their bags ahead of Wednesday's inauguration. This week marks her dad Donald and First Lady Melania Trump's final week in office, before president-elect Joe Biden moves into the White House with new First Lady Jill Biden.

This will be the B'den's second time wheeling in their suitcases into the White House, as the pair previously lived in the iconic building for eight years during Barack Obama's years in office. The troubled outgoing President is the first commander-in-chief to be impeached twice, and could be banned from standing for office ever again.

He incited a siege at the US Capitol building on January 6 which led to five deaths, including that of a police officer trying to control crowds. Biden is expected to deliver a speech aimed at bringing Americans together as A list stars gear up to perform in honour of the new president.
