On Sunday, he reassured his fans that he and Vanessa, 34, are OK.
"For the record, @VanessaLachey and I are both fine after our little @uber accident," he tweeted. "Just a sobering reminder to always buckle up!"
Thankfully, the couple's adorable children -- three-year-old son Camden John and ten-month-old daughter Brooklyn Elisabeth -- were left at home. Vanessa gave birth to their adorable daughter in January.
Still, we hope the mishap doesn't stop Nick and Vanessa's adorable date nights! The two have been married since July 2011, but still manage to look more smitten with one another than ever.
