The 41-year-old singer has revealed he and his stunning spouse, 34, whom he married in 2011, were on their way to a dinner date when the Uber car they were travelling in was involved in a minor smash up with another vehicle.

Taking to his Instagram account last night (11.10.15), Nick uploaded a photograph of a white car's scrunched up bonnet sitting under a black vehicle's caved-in boot, but refused to state which motor he was travelling in at the time.

Offering some safety advice to his fans, he wrote: "Word of advice.....always wear your seatbelt when you @uber There is no such thing as a guaranteed safe ride. #datenight (sic)."

After being bombarded with a string of concerned messages from his social networking followers, the former 98 Degrees star assured fans he and Vanessa were safe and well.

He added: "For the record, @VanessaLachey and I are both fine after our little @uber accident. Just a sobering reminder to always buckle up!"

Meanwhile, the couple, who have three-year-old son Camden and 10-month-old daughter Brooklyn together, previously admitted they try to go on regular date nights to keep their romance alive.
