After performing "That Girl" at his concert on Sunday in Louisville, KY, Justin Timberlake paused the show to invite two lucky fans, Josh and Kim, on stage.

Unbeknownst to Kim, Josh contacted the singer's management team last month asking if he could propose on stage at the concert, and Timberlake happily agreed. Watch the sweet video:

Timberlake could barely contain his excitement for the newly-engaged couple:

I love Pinterest just as much as the next bride — I currently have 9,255 pins (and counting) to prove it! This borderline obsession of mine isn't going anywhere anytime soon. According to Splendid Insights, a wedding lifestyle market research firm, 78% of U.S. couples that got married in 2012 used Pinterest to help plan their wedding.

Here's how to use Pinterest throughout the course of your wedding planning:

1. After you first get engaged, pin anything (and everything) you like with no limitations.

When you first start planning your wedding, Pinterest can open your eyes to a ton of inspiration you might not have seen otherwise. It exposes you to different wedding styles, color palettes, and ideas, and hopefully, it'll help you gravitate towards a specific vision. As a wedding planner, I’ve found that it can be an extremely valuable tool when planning.  

2. Look for similarities in your inspirational wedding images.

It's been a crazy two weeks for me, and I'm sure it's been the same for all of you. But I have good news to share: I reached my 10 pound weight-loss goal for November! And now, I have my sights set on losing another 10 by January 1.

In the past few weeks since Thanksgiving, there have definitely been some challenges and hardships with staying on track, but I've managed to get through them and keep on keeping on.

Things I've learned:

1. One bad night of eating won't kill you, but it does curb the weight loss and make it tougher to go back to making good decisions.

I went to Atlantic City two weekends ago with three of my sorority sisters and had a blast! We don't all live in New York, so once a year we get together — and this year, we sure did it right. I messed up as soon as I got there with my lunch, where I ate nachos and French fries. We went to Buddhakan for dinner and had some tapas (I highly recommend the restaurant), then proceeded to Royal Jelly, the burlesque club at Revel, where we had a VIP table. I drank vodka and Red Bull, which I know is so unhealthy on so many levels. After we went out, I ate a half of a turkey burger and French fries at like four in the morning. I was eating like I weigh 100 pounds, which I totally don't.

What could be better than to celebrate your engagement and the holidays at the same time? These two parties struck the perfect balance between incorporating Christmas themes and reflecting the couples' personalities. 

Theme: Tacky Christmas Party

Lauren and Drew first met at a Tacky Christmas Party, so when the couple got engaged four years later, the bride-to-be's best friend, event planner Katie from Kate & Company, knew it'd be the perfect theme for the couple's engagement party — made even more amusing because the party took place in July! Katie incorporated some of the couples' family holiday traditions — like a "find the pickle" game and Grandma's famous potato salad — as well as favorite quotes from Christmas movies, a beer can Christmas tree, milk and cookies for Santa, a Charlie Brown Christmas tree centerpiece, and so much more.
