According to TMZ, the R&B star will lend his voice to the celebrations when the "Sorry" hitmaker, 25, and 22-year-old model mark their union in South Carolina with family and friends.
Sources told the publication that the couple settled on the crooner because of his Canadian heritage, and also claimed he's the pair's favourite singer at the moment.
While rumours had circulated their pal Ed Sheeran, who duetted with Justin on the chart-topping hit "I Don't Care" earlier this year, could make an appearance, insiders told the publication there are no plans at present.
The couple officially tied the knot in an intimate ceremony late last year, and Hailey's father, actor Stephen Baldwin, previously told TMZ the second wedding will be all about marking the religious importance of marriage.
The "Usual Suspects" star, 53, also confirmed he'll walk his daughter down the aisle on the day.
