Always inventive, singer, trendsetter and superstar mommy Kelis seems to do things in her own time and in her own unique way or not at all. After taking a hiatus to have a baby, split with her former husband Nas and study culinary arts, she’s back with new music–a full album is coming soon–and a funky mullet hairdo to match. Kelis released her single “Acapella’ on Twitter and launched a new site,, today. Add the minimalist, upbeat track to your feel-so-good-day soundtrack.
