Donald Trump Jr's Eldest Daughter Kai Melts Hearts with Sweet Tribute on Brother Donnie's 11th Birthday

Fans gushed over a sweet tribute posted by Donald Trump's Jr eldest daughter to her eleven-year-old brother Donald Trump III on his birthday.

There is nothing more adorable than the affection between two siblings. Recently, Donald Trump Jr's eldest daughter, Kai Trump shared a sweet birthday tribute for her bother, Donald Trump III, in her caption she wrote:

"Happy birthday Donnie I love u so much. You are my favorite and best friend. Love u! ❤#11."

The simple yet sweet message was accompanied by rarely seen pictures of Donnie overs the years. It ended with image of Kai and him standing in one of the rooms in the White House. Gushing over the delightful post, one fan said:

"What a beautiful sentiment you have for your brother. Your dad and mom have done a wonderful job in raising you and your brothers and sister. Happy birthday to Donnie."

While many people also joined her in wishing Donnie a happy birthday, the compliments directed at Kai didn't stop there.

One fan found her tribute to be "cute" and praised the twelve-year-old for sharing messages and showing how much of a good sister she is to her younger sibling.

While fans gushed over how adorable the pre-teens looked there was a lot of debate over who the siblings looked like in the Trump family.

One fan noted that Donnie looks a lot like his father in younger years. Another fan couldn't get over the sweet gesture and joined more people in praising her for being so affectionate.

Kai is the oldest of five children from Donald Jr and his ex-wife Vanessa. The couple was married in 2005 in a lavish wedding at President Donald Trump's private beach club, Mar-A-Lago.

In March, she filed for an uncontested divorce. They have managed to keep to their word when they announced the split that they would not have a messy divorce or custody battle.

The couple has done the best to keep a civil co-parenting relationship when the decision to go their separate ways and avoid giving in to the media backlash over their fallout.

Donald Jr has since been dating Kimberly Guilfoyle from Fox News. They made their relationship official shortly after his divorce.
