Ivanka Trump congratulates brother-in-law Josh Kushner and Karlie Kloss on getting married

Karlie Kloss and Josh Kushner got married on Thursday, October 18, in a top-secret wedding attended by a reported 80 people.

Though it's unclear exactly who was there, we do know that Kloss' pal Taylor Swift wasn't in attendance, as she had to take an 18-hour flight to Perth, Australia, for her latest stop on the Reputation Stadium Tour -- news she revealed in a colorful Instagram Story.

With the question of whether or not Swift was at the upstate New York wedding answered, the next potential guest that people wanted to know about was Ivanka Trump, who is married to Josh's brother, Jared Kushner. Right now, it's unclear if Trump was in attendance at the nuptials (The Daily Mail reports that she did attend along with her husband and three children), but the First Daughter did take to Twitter to congratulate the happy couple on their wedding, which came just four months after Kloss announced their engagement.

"So much love for you both as you begin forever together," Ivanka tweeted in response to Kloss' simple wedding announcement, which included a photo of the pair together at their wooded venue.

Trump had previously given the couple a public show of support when Kloss revealed their engagement to the world over the summer.

"So, so happy for you and Josh!" Ivanka wrote back in July. "I feel blessed to have you as a sister (!!!) Karlie and look forward to the decades of happy memories we will create together as a family!"

"So incredibly happy for you Josh," the advisor to the president wrote on Josh's engagement announcement. "You and Karlie are blessed to have found one another. Here’s to a lifetime of love, laughter + adventure for you both!"

Though Kloss has never publicly addressed her relationship with her now-sister-in-law, the two did attend the 2016 US Open together with a mutual friend, and sources claim that they've been friendly since 2012. Josh reportedly refers to Ivanka as his "sister" (instead of "sister-in-law"), and Newsweek insists that he is close with Jared and Ivanka, despite their vastly different political views.

Indeed, Kloss and her husband have said in the past that they share the same "liberal values" and that they've chosen to spend their lives together "despite complications," alluding to their connection to the Trump family.
