It's a bittersweet week of news for Ellie Goulding fans.

The singer announced on Instagram that her performance at Norwich Sundown Festival this past Sunday had been her "last festival of the summer and last show for a long time."

While Goulding is said to be working on her next album, fans may soon have something to hold them over during her hiatus, as Iggy Azalea took to Twitter on Thursday to reveal the pair has a "nice little numberrrr together" on Azalea's forthcoming deluxe version of her major label debut album, The New Classic, which was released earlier this year.

The Goulding collaboration will be one of six new tracks on the updated set.
