They've been on a whirlwind tour of London, Italy and Canada after getting a marriage license in New York City.
And on Sunday, Justin Bieber introduced Hailey Baldwin as his 'wife' during a visit to an exhibit dedicated to his career in his home state of Ontario.
The Windsor Star newspaper reported that officials at the Stratford Perth Museum said on social media that Justin 'very graciously introduced Hailey as his wife' during the visit.
Heartfelt: Justin Bieber introduced Hailey Baldwin as his 'wife' during a visit Sunday to the Stratford Perth Museum in Ontario and left a gushing note to her at the exhibit about his career
The Canadian pop star also left a message on a chalk board where his fans leave messages after viewing the exhibit and staff posted it to the museum's Instagram on Monday.
The caption read: ' 'I <3 you forever-Hailey B'. We were so pleased to have such a warm and special guest visit the museum yesterday (along with her very special husband) @haileybaldwin @justinbieber.'
Justin's grandparents live in Stratford and the museum's general manager John Kastner told the Windsor Star that he and Hailey spent about 45 minutes mingling with fans at the exhibit, which showcases memorabilia from the 24-year-old singer’s tours and early years in Stratford.
Later on Sunday, the celebrity couple were seen arriving at a local airport where they boarded a private jet.
Justin and 21-year-old model Hailey, who got engaged in July, have kept fans guessing about their marital status.
In September, People rpeorted that they had married while at the courthouse in new York before jetting off to Europe.
However, Hailey later denied on social media that they had exchanged vows.
As it seems they are now heading back to the US, it remains to be seen if they will publicly confirm they are indeed husband and wife, as Hailey's uncle Alec Baldwin told Access at the Emmys, or if they are planning a religious ceremony where they will exchange vows in front of family and friends, as has also been rumored.
