With all the shows, red carpets and public appearances Lorde has made over the past year, it's not too surprising that all the action in her life would eventually catch up with her. So much so that she's come down with a chest infection and had to cancel the Australian leg her tour.

She announced the news in a series of tweets.

Lorde finished her message by apologizing to fans for having to cancel the dates. "I'm truly sorry if i let you down or if you feel inconvenienced by this and i hope you can understand. x," she tweeted.

In the last month, Lorde has played Coachella and Lollapalooza's South American, and joined the surviving members of Nirvana at the Rock and Roll Hall of Fame induction ceremony.

After some bed rest, she's scheduled to come back to the U.S. to play Lollapalooza, Oshega and the second weekend of Austin City Limits.

In the meantime, check out her performance of the inescapable 'Royals' from Coachella last week:
