Tiffany Trump and her billionaire boyfriend Michael Boulos not only spent the Thanksgiving holiday together, but they also enjoyed a night out at the Kuwait-America Foundation's gala dinner in Washington, D.C.

The first daughter's 22-year-old beau took to Instagram on Monday to share some throwback photos of himself with his ladylove at the annual event for UNHCR, which took place at the Kuwait Embassy on November 18.

Tiffany, 26, looked glamorous in a figure-hugging black gown featuring a plunging neckline and a slit while attending the gala, during which U.S. Secretary of State Mike Pompeo was honored with the Humanitarian Award.

Tiffany shared Michael's post on her Instagram Story on Tuesday after returning to Georgetown University the day before to finish the last few weeks of the fall semester.

Ten days after they attended the gala together, they headed to Alabama to spend Thanksgiving with Tiffany's mother, Marla Maples.

The couple skipped out on the Mar-a-Lago celebrations with her dad and half-siblings, having spent Thanksgiving at his Florida resort last year.

This time, Tiffany flew down south to take in the turkey day feast with her 56-year-old mom, bringing along her billionaire beau for the fun.

Tiffany and Michael kept social media posts to a minimum, though both have shared photos and video of the Alabama outdoors.

Tiffany and Michael have been in a long-distance relationship since they started dating a little over a year ago.

While she is attending law school in D.C., Michael has been based in London, but it's possible that he moved.

On Sunday, the same day Tiffany traveled back to D.C., he shared a photo of himself with two of his friends in Marylebone, a neighborhood in the West End of London.

'TB to them London days,' he captioned the image.
