While attending the launch of Piperlime in West Hollywood on Wednesday, Sports Illustrated model Chrissy Teigen opened up about spending "forever" with singer John Legend, whom she married a year ago following nine years of dating, Us Weekly reports.

"I think you are just more comfortable talking about the future more," Teigen told Us Weekly about life after marriage. "I was the kind of girl that never talked about marriage and kids ... [Now] you just end up talking about everything as forever which is very cool."

In addition to expressing her happiness over married life, Teigen also expressed her excitement over the idea of her husband needing Viagra in the future.

"It's nice to be able to be like, 'I can't wait to see you with gray hair, it's going to be hysterical.' Or, 'I can't wait until you have to use Viagra, that's going to be hysterical!'" she teased.

Tiegen also opened up about her plans to expand her family with hubby, John Legend.

"I want a huge family," Teigen continued. "We want a lot of kids. When it happens, it happens. For us it's hard because he's on the road so much and I'm working. People think it happens so easily ... but the stars really have to align to have a baby and it is a little miracle so when it happens ... we will be so happy."

Prior to their marriage, Teigen and Legend sat down with Oprah Winfrey to talk about their wedding plans and Legend's decision to propose to Teigen after many years of dating.

"I knew I loved her. I knew I could see myself living with her and spending time with her forever. I knew I could envision us having kids together and I felt like it was time to propose," Legend told Oprah.
