A mural in Melbourne apparently proclaiming "the death" of Taylor Swift has been painted over.

The popstar's likeness was painted in a famous graffiti-covered laneway alongside the name "Taylor Smith".

It appeared earlier this week amid the Bad Blood singer's escalating feud with Kanye West and Kim Kardashian.

The mock memorial now has a cartoon face scrawled over it and the words "In loving memory of Harambe", the gorilla shot dead by zookeepers in the US.
