The couple announced their engagement last month after meeting in February 2012 while recording Lavigne's latest album.
Speaking to Hello! Canada, the Nickelback frontman said he found it "embarrassing" to break the news of his forthcoming nuptials to his parents via phone as he had never introduced Lavigne to them.
"You never know what your parents are going to say when you tell them you're getting married - especially when it's with someone they haven't met yet!" Kroeger explained.
"My mum is a huge fan of Avril's, so putting her on the speaker phone and telling her the news was hilarious and equally embarrassing."
Lavigne added: "Everyone is super stoked for us. The reaction from our friends and family has been awesome!"
The pair are said to be "enjoying" their engagement and have not yet planned their wedding date.
