Nick Lachey admitted his divorce from Jessica Simpson left him with some scars.

The TV personality opened up about his split from the singer in 2006 in the third season of “The Ultimatum,” released on Netflix on Wednesday.

Speaking to a contestant about her fear of marriage, he said: “I too have been married and divorced before, so I understand the pain and scars that come from that.”

Nick, 51, explained he had to put his fears aside when he met his now wife Vanessa Lachey in July 2011 and ultimately decided to marry her.

“Don’t let your past dictate your future,” he said, according to E! News.

“What I have really always wanted in my life is a beautiful marriage and a beautiful family. If I didn’t believe in it, I would never have experienced the beautiful life I have with this woman.”

The dating series – hosted by Nick and Vanessa – features couples who come together to decide whether to marry each other or break up.

Nick and Simpson began dating shortly after meeting at a Hollywood Christmas parade in 1998.

In February 2002, the “Love is Blind” host popped the question to the 44-year-old “Dukes of Hazzard” actress in a very romantic way, she announced on her website at the time, per People.

“He had been patiently waiting for me to grow up a little (which I needed). And I have that! Now my life feels so perfect.”

The exes married in October and showcased their imperfect romance on their 2003 reality show “Newlyweds.”

The series depicted difficult moments in their relationship, with Lachey portrayed as the best husband and Simpson as dorky.

In 2006, the two released a joint statement saying that after “careful consideration and consideration,” they had decided to separate, according to People.

That same year, Nick moved in with 44-year-old Vanessa and they married five years later. They share Camden John (12), Brooklyn Elisabeth (9) and Phoenix Robert (7).

Simpson married Eric Johnson in 2014 and the two share Maxwell Drew, 12, Ace Knute, 11, and Birdie Mae, 5. It is rumored that the two are getting divorced.
