Lauren Conrad is over the hills in love! The reality star turned designer and author got engaged over the weekend to boyfriend of nearly two years, William Tell. Conrad debuted her big sparkler on Instagram Monday morning, and we think it's simply gorgeous! Her ring features a round-cut diamond on a simple platinum band, and she showed it off next to a perfectly placed Sydney Evan “Love” ring (which you can pick up for yourself at; plus, shop more scripted "love" rings here). "I am beyond thrilled!" Conrad wrote of her engagement on her personal blog. "Get ready for lots more wedding content here on as we begin the planning process." We can't wait for all the behind-the-scenes looks at Conrad's big day that are sure to come, and send our congratulations to the lovely couple! Now that you’ve seen the ring up close, tell us: What do you think?
