Lana Del Rey has favourited a tweet containing a picture of a bracelet made of pins captioned, "I bought this for you @lordemusic."
The unpleasant tweet came from the fan site 'Lana Del Rey News' and is one of just three tweets the singer has favourited in the past week.
Lorde has been somewhat critical of Del Rey in the past, though she has since clarified her stance. The New Zealand singer said last year, "What really got me is this ridiculous, unrelatable, unattainable opulence that runs throughout."
She added, "Lana Del Rey is always singing about being in the Hamptons or driving her Bugatti Veyron or whatever, and at the time, me and my friends were at some house party worrying how to get home because we couldn't afford a cab. This is our reality."
Lorde subsequently tweeted saying, "Just because their songs aren't my reality (being 17 and from Auckland) doesn't mean I don't admire their musicianship and careers!"
It seems Del Rey didn't take too kindly to the comments though, and her decision to favourite the tweet aimed at Lorde has prompted criticism on twitter.
Neither Lorde nor Lana Del Rey has actually commented yet on the slightly passive-aggressive move.
