The Young Victoria star's former flame Michael Bublé is engaged as well.
The 34-year-old Canadian crooner is betrothed to 22-year-old Argentinian actress Luisana Loreley Lopilato de la Torre, who he's been dating since November 2008, his rep, Liz Rosenberg, confirms to E! News. The pair met at a party following one of his concerts in her hometown.
"Michael proposed to his girlfriend, Luisana, in November in front of her family in Argentina," Rosenberg tells People. "They're ecstatic. They're adorable, in love and laugh all day long." No date has been set.
The bride-to-be stars in a popular South American soap opera and in Bublé's recent video for "Haven't Met You Yet."
Bublé was once engaged to singer-actress Debbie Timuss, but the pair split in 2005. He and Blunt dated for two years before calling it quits in 2008.
