Who's the boss? Sinead O'Connor, clearly. The "Nothing Compares 2 U" singer unveiled a dramatic, super-glam new makeover on Monday, June 2, to go along with her upcoming album, I'm Not Bossy, I'm the Boss, due out Aug. 12.

Rocking a sleek, jet-black bob with blunt bangs, the Irish chanteuse, 47, is virtually unrecognizable on the cover art for her LP. With her smoky eye makeup and sexy PVC leather frock, she looks a bit like British diva Jessie J—a far cry from her usual no-fuss, shaved-head self.

In a post about the new album (and its stunning promo pics), O'Connor explained that the title was inspired by Sheryl Sandberg's "Ban Bossy" campaign, which aims to empower young girls to be leaders in part by changing the way we talk about them.

"Originally I had a different title, The Vishnu Room," the singer-songwriter wrote on her website, "but a few months back when I saw the phrase 'I'm not bossy, I'm the boss' and became aware of the Ban Bossy campaign, I wished I could re-name the album, since indeed it can be tricky being a female boss and I think Sheryl's campaign is a terribly important one."

"At the stage I became aware of the Ban Bossy campaign, it was too late to change the album title because the sleeve was already in print," she continued. "But last week when the record company received the promo shots, which included the cover shot you now see, they asked could they change the planned cover to the current one, and that allowed me the opportunity of changing the title."

I'm Not Bossy, I'm the Boss is O'Connor's 10th studio album. Her last LP, How About I Be Me (And You Be You)?, dropped in 2011. Her new single, "Take Me to Church," will be released on the same day as the new record.
