Kristin Cavallari and Jay Cutler married back in 2013 and already have two children–with number three on the way. Theirs was definitely a case of love at first sight.

On Tuesday, during a question and answer session hosted on Twitter by both Revlon and Cosmopolitan, the star of The Hills and Laguna Beach shared relationship advice and talked about how quickly things heated up between her and Cutler–before they were husband and wife.

In addition to relationship questions, Kristin Cavallari also talked makeup with the Twitter fans who checked in for the Q & A session.

People seemed far more interested in her relationship talk, however.

Kristin Cavallari’s relationship advice–whether or not that relationship involved love at first sight–is definitely sound.

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 since

Kristin Cavallari realizes that living her life in the spotlight makes her a target for the paparazzi. Fortunately she has never paid attention to much that’s been printed about her and Jay Cutler. Cutler had a hard time adjusting to the paps, however.

The pop culture world was all new for Jay so paparazzi bothered him (still does) and it took a lot of adjusting. He wasn't used to ppl….

Love at first sight is great–but longevity is even more important. It sounds like Kristin Cavallari and Jay Cutler likely have what it takes to make their love last.
