Nick Lachey has paid a gushing tribute to his "incredible" wife Vanessa Lachey on their 14th wedding anniversary

Nick - who has sons Camden, 12, and Phoenix, eight, and 10-year-old daughter Brooklyn with Vanessa - wrote on Instagram: "14 years ago, I said I Do to a life with this incredible woman. On that day, we started a journey that has brought us three amazing children and the family I always dreamed of. V, there is nothing we can't accomplish together and I can't wait to see where we go next.

"I love you and the life we have together. (sic)"

Nick admitted their relationship "isn't always perfect" or "easy", but he loves Vanessa "more than any post can express".

He added: "It ain't always perfect and it ain't always easy, but we continue to figure it out!! I love you more than any post can express. Happy Anniversary babe! (sic)"

Vanessa responded with several heart emojis, and she also wrote a message on her own Instagram grid.

She posted: "19 years together, 14 years married (today) I'm FOREVER Yours Faithfully! Happy Anniversary, My Love! (sic)"

The pair met on the set of MTV's Total Request Live, on which his band 98 Degrees made regular appearances and Vanessa was the host of the show.

Nick and Vanessa now co-host dating show Love is Blind together, and he recently admitted he loves working with his wife.

He told E! News: "The show gives us an opportunity to not only do something we love and be a part of a show we love but to also work with people we love.

"I get to experience it in 98 Degrees. Working also my brother [Drew]. I get to experience it with Vanessa on the show."

Vanessa quipped: "Did you just compare me to your brother?"

Nick replied: "People I love! Not clearly that in the same way, not in a Valentine's Day kind of way!"
