Looks like Lorde may be driving a Cadillac in real life pretty soon: Billboard reports that she's signed a publishing deal worth $2.5 million.

The deal is with SONGS Music Publishing, which confirmed it in a statement saying, "When all is said and done, [Lorde] will go down as one of the greatest lyricists of all time."  It's Billboard, however, that's put a price tag of $2.5 million on the deal, citing sources familiar with the negotiations.

The deal gives SONGS Music Publishing the rights to administer the songs on Lorde's debut, Pure Heroine, as well as those on her EP The Love Club, and future recordings.  Billboard reports that the singer was the subject of a months-long bidding war, and that the deal was signed on November 7, her 17th birthday.
