Ivanka Trump’s Son Joseph Celebrates 13th Birthday With White House Dinner Hosted by President Trump

President Donald Trump‘s grandson Joseph Kushner is officially a teenager, and he marked the milestone in style at the White House.

The president’s daughter Ivanka Trump — whom he shares with late ex-wife Ivana Trump — shared a carousel of Instagram photos on Thursday, October 15, offering a glimpse of her middle child’s birthday celebration with his grandfather, 80.

Joseph, whom Ivanka shares with husband Jared Kushner, turned 13 on Wednesday, October 14.

“An unforgettable birthday dinner for Joseph, hosted by Grandpa at the White House,” the businesswoman, 44, wrote in the caption. “Thirteen is off to quite a start!”

The first snapshot shows Ivanka, Joseph and the Apprentice alum smiling at a dining table in the Red Room. Another captures the birthday boy leaning in to blow out a candle on his dessert. Ivanka wore a long navy dress, while Joseph and his grandfather coordinated in blue suits and ties.

Joseph’s father, 45, was behind the camera for one of the dinner photos, but he joined his wife and son for a family portrait in another area of the White House.

Other pictures showed Joseph posing outside the White House and spending time with his grandfather in the Oval Office. In one photo, the teen peers over the president’s shoulder as they flip through an album with the two of them on the cover.

It’s been a busy season of family celebrations for Ivanka. Her own birthday falls on October 30, and earlier this month she celebrated a far bigger milestone: her maternal grandmother’s 100th birthday.

On October 2, she posted photos of herself and brothers Don Trump Jr. and Eric Trump gathered with their spouses and all 10 of their children to toast Marie Zelníčková, known to the family as “Babi.” She is the mother of the late Ivana, the president’s first wife.
