Karlie Kloss and Joshua Kushner are engaged: All the details

After six years together, Karlie Kloss and Joshua Kushner are officially engaged!

"I love you more than I have words to express," Karlie wrote on Instagram Tuesday. "Josh, you’re my best friend and my soulmate. I can’t wait for forever together. Yes a million times over."

Although they're now happy to share the big news, the couple reportedly kept their engagement under wraps for about a month. Kushner, 33, proposed to Kloss, 25, during a "romantic weekend together in upstate New York" weeks ago, People reports.

The supermodel also in June converted to Judaism, a process that can take months (or longer) to complete. A few years ago, Joshua's sister-in-law, Ivanka Trump, converted before marrying his brother Jared.

Karlie and Joshua have mostly avoided wading into politics since Jared and Ivanka took their positions in the White House, but the First Family members will almost certainly attend the nuptials.

Buzz is already beginning about which other famous faces will snag an invite. Not so long ago, Taylor Swift would have been a shoe-in for the bridal party -- but reports about an icy falling-out have circulated for about a year, and neither lady has explicitly addressed the rumors.

“It’s not like I’ve ever wanted to be so secretive about my private life," Kloss said earlier this year. "Carolina Herrera always says, ‘A woman who’s an open book is boring.’ There’s no mystery anymore. I know in my life what really matters to me. I’m not trying to hide that from the world; I just really like having a more private private life. I’ve got nothing to hide, though."

We're all for keeping things private... but hopefully she'll spill a few details before the big day!
