HOLLYWOOD, Calif. — Michael Bublé has hit another high note!

The Canadian crooner is now engaged to his girlfriend, Argentinian actress Luisana Loreley Lopilato de la Torre, his rep revealed Sunday to People.

"Michael proposed to his girlfriend, Luisana, in November, in front of her family in Argentina," said publicist Liz Rosenberg. "They're ecstatic. They're adorable, in love and laugh all day long."

Bublé, 34, and Lopilato, 22, met after one of the singer's concerts in Buenos Aires in November 2008. They have yet to set a wedding date.

Bublé was previously engaged to singer and actress Debbie Timuss. After the pair split in 2005, he had a high-profile relationship with actress Emily Blunt for two years.
