President Trump's five-year-old grandson Tristan broke his leg skiing on a jaunt to Aspen this weekend.

TMZ reports that the second-youngest son of Donald Trump Jr. fractured his leg on Sunday and that Secret Service accompanied the boy to the emergency room.

Donald Jr and sister Ivanka took their families to the Colorado ski resort this weekend for some alpine fun away from Washington, DC.

It appears that Tristan had already hurt himself by the time Ivanka treated the kids to some après ski ice cream Sunday afternoon.

Ivanka was seen holding her one-year-old son Theo and walking through the streets of Aspen while her nieces Chloe and Kai, nephew Spencer, daughter Arabella and son Joseph tagged along and chowed down on their own cones.

Missing from the scene was Ivanka's husband Jared Kushner, who appears to have stayed home and was pictured leaving bright and early Monday morning for work at the White House.

After lunch at the Trendy Ajax Tavern Sunday afternoon, Ivanka was pictured meeting up with her bother and his wife Vanessa for some shopping at Club Monaco.

Ivanka wore a chic black tracksuit during the family outing and sported reflective sunglasses. Both Trump children were spotted periodically checking their phones after a busy week.

On Friday, the First Daughter met with German Chancellor Angela Merkel where she joined in on a conversation on how companies can better train workers.

Unlike his sister, Donald Trump Junior said at a GOP fundraiser that he has 'basically zero contact' with President Trump .

Ivanka moved to Washington, DC, when her husband was appointed senior adviser to the president. Donald Jr and Eric are based in New York City, and continue to run the family business.

Secret Service agents were also spotted in Aspen where the Trump siblings spent the weekend with their families. There are an estimated 100 Secret Service agents present to look after the first family.

The Trump children took an Aspen vacation in 2015 months before their father announced his candidacy for president.

It is not clear what Tiffany Trump's plans were this weekend.

Saturday, Donald Trump Jr shared a clip of him jetting off to a weekend in Aspen from LaGuardia in New York City.

He wrote in the post his children were helping with the takeoff, suggesting they were in the cockpit with him: 'Kai and Donnie helping fly Trump Force One. Little takeoff action at LGA this evening. Family spring break.'

The Secret Service has denied paying $12,000 to an Aspen ski resort ahead of President Donald Trump's children's visit, despite a telling contract showing up on a federal website.
