Nickelback Singer Doesn't Care About 'World's Opinion' Of His Engagement To Avril Lavigne

'We can't wait to start our life together,' Chad Kroeger tells People.

July 1 is not just an important day for Canadians, it's also extra-special to two of the country's stars, the recently engaged Avril Lavigne and Nickelback frontman Chad Kroeger¸ who decided to take their professional relationship to the next level on Canada Day.

"We think it's very cool that our anniversary will always be on Canada Day," Kroeger told People magazine, in the issue featuring "Jersey Shore" star Snooki and her baby, Lorenzo, on the cover. "We can't wait to start our life together."

In the magazine (hitting newsstands Friday), Kroeger explained that he doesn't care what people think about his relationship with Lavigne, whom he started dating earlier this year after they linked up to record music for her album. The couple's relationship basically flew under the radar until they announced their engagement last month. "I try not to take too much interest in the world's opinion of our relationship," Kroeger said. "I just know the both of us are very happy."

Before they walk down the aisle, Kroeger and his bandmates will be hitting the road with Daughtry, and Lavigne has an open invitation to come hang out with her fiancé on the road.

"She'll come over and spend some time [with me] when she's got time," he said. "They're going to throw a lot of stuff on her plate with the new record."

It was only five weeks after Kroeger and Lavigne began dating in July that Chad asked the pop star to marry him on August 8 with a 14-carat diamond engagement ring. "A romantic relationship blossomed as they spent time writing together," a friend of Lavigne's told People. "He makes her so happy," a friend of the Lavigne family added. "Both of their families could not be more excited."
