*Singer Kelis has a reputation for being bold and bossy. She usually gets what she wants. Just ask her recent ex-husband, rapper Nas.

You would think that with that kind of attitude, she could be expected to act like a total diva. Maybe so, but it’s been four years since the “Milkshake” singer, who’s raising her son on her own since splitting from Nas, has released an album. She would have been excused had she decided to delay the album again (set for release this Tuesday, 07-06-10), but as it turns out, it was her bundle of joy that kept her on track. Here’s what she told New Music Reviews:

“I was actually extremely pregnant and totally on my own when I started this album,” says Kelis, 30, who has hired help to assist with Knight while she does promotion and tours. “I had just gotten off my last label and hated the music industry. But a friend of mine from the U.K. was like, ‘You should be writing.’ So, I started writing and he started sending tracks, like the David Guetta stuff, and I just started falling in love with my stuff.”
