Kristin Cavallari knew Jay Cutler was "The One" almost immediately.

The 28-year-old designed revealed as much in a Q&A session hosted by Revlon and Cosmopolitan on Twitter. Cavallari and the 32-year-old NFL star fell hard for each other after they started dating in late 2010.

"We moved really fast. He told me loved me after 2 wks & that he wanted 2 marry me aftr 2 months. I knew right away!" she tweeted. "The 2nd time I ever hung out w Jay we decided to go to Nashville last minute and had the best 24 hrs! It was the most fun I've ever had."

Cavallari and Cutler got engaged in April 2011, and separated in July before reconciling in November of that year. The couple married in Nashville in June 2013, and have two sons: two-year-old Camden and one-year-old Jax.

"We're pretty boring and make dinner at home but wait to eat until after the kids go to sleep so we can connect," she said of their date nights. "Light candles and put phones away. Take a bath (doesn't even have to be sexual..or it can!) but it's all about talking and connecting."

Cavallari and the Chicago Bears quarterback announced they are expecting their third child in May. The couple recently attended the 2015 Bears Care Gala, and celebrated their second wedding anniversary with a throwback photo Monday.
