Lorde has apologised for posting a picture of a bathtub and a quote from a Whitney Houston song.

The New Zealand singer posted the caption “And iiii will always love you” under her Instagram photo.

People were quick to point out that Whitney was “Found underwater” in a bath when she died in LA in 2012.

The 21-year-old added: “I’m an idiot. Love Whitney forever and ever. Sorry again.”

One of Whitney Houston’s most famous songs is I Will Always Love You, originally written by Dolly Parton.

Whitney’s later career was overshadowed by substance abuse and her turbulent marriage to singer Bobby Brown.

Lorde, currently on tour in the US, said she used an “Extremely, extremely poorly chosen quote” for her Instagram picture.
