The 29-year-old singer, who married the rocker in July is currently working on her fifth studio album which is believed to be released on November 5, reported People magazine.
"I do (feel pressure to start a family) now that I'm married. I want to be ready. I'm focusing on my music. I'm just releasing a new record. This is my priority and my baby right now," Lavigne said.
The singer's relationship to Kroeger, who is the frontman of the band Nickelback blossomed after they began working together in 2012 to write and record music for Lavigne's fifth album.
'Rock N Roll' singer likes collaborating with Kroeger.
"He proposed in the studio so it was really romantic, and when we work together, we're creating and we're in the moment of making something happen, so it's fun," she said.
"The hours are long, but it actually just makes that process even better because he's there with me, so I like working with him. Plus I think he's a really talented song writer and I respect him and his work tremendously," she added.
