Unfortunately, however, we're not sure the fashion risk paid off. The anchor-print jumpsuit by Malene Birger should be cool, but somehow ended up just looking like oversized nightwear on the mezzo-soprano. Thumbs up to the neon-pink heels, though.
She did seem to have something to celebrate, however, posting on Twitter: "Happy Day #NewChapter #ILoveMyJob."
Katherine famously split with her record label Warner three months ago, so perhaps a new project is in the pipeline.
She also posted a pic of herself clinking glasses with a friend, writing: "Cheers! #Celebrating."
Congrats Katherine! (Even though we don't know what you're celebrating...)
