Nick Lachey and Vanessa Lachey's Relationship Timeline

From co-hosting multiple hit Netflix reality shows to raising their three children together, Nick and Vanessa Lachey are an impressive pair.

The longtime couple first met on the set of MTV's Total Request Live. Vanessa, born Vanessa Minnillo, was a host on the show, while Nick regularly made appearances with his band 98 Degrees. At the time, Nick was still married to his first wife, Jessica Simpson, whom he separated from in 2005.

"I'll be like, 'Who's going to pick him up today? All right, you got it,' " Vanessa added.

From competing against one another on season 25 of Dancing with the Stars to co-hosting Netflix's reality hits Love Is Blind and The Ultimatum, the duo continues to show their support for one another. Here's everything to know about Nick and Vanessa Lachey's relationship.

"[The] video, which was on TRL, was the beginning of our relationship. That's what made it no longer friends and it got romantic. To the point that if you go back and look at the video, when he came to premiere it, I was so nervous and so crushing him that I didn't show up for work that day. I called in sick," she explained.
