In an interview with Power 106 Los Angeles, Austin revealed that he knew there was something special about Catherine from the get-go. Immediately, Austin wanted something serious, but Catherine took a minute to warm up to him. She didn't even hug or kiss him on the first date! However, they continued to see each other, despite Catherine's hesitations. "I just wasn't used to like, things happening so quick, and things being so real so quick," she said in the interview. 

They welcomed their daughter Elle in 2016 right before launching their YouTube channel, which they titled using the first initial of their three names. The family has been documenting their daily lives over the past few years to their over 17 million subscribers and counting. Their channel has been such a success that they've even signed a contract with Univision to join its Creator Network, as exclusively reported to Variety.
