New Zealand pop star Lorde shunned a big party for her 18th birthday and instead spent the milestone at home with her family.

The Royals singer hit the landmark age on Friday (07Nov14), but she decided not to host a big celebration.

She tells the Sydney Morning Herald, "I was just at home, with my family, eating cake."

After her big day, Lorde sent a message to fans thanking them for all their support, writing in a post on, "Thank you all for the birthday wishes, I had a lovely day."
