On the eve of her World Tour with the Discipline album Janet Jackson has launched her signature lingerie brand Pleasure Principle, named after her 1987 hit single.

With this the 42-year-old singer, songwriter, actress, dancer and record producer becomes a designer as well — in partnership with Australian designer Bruno Schiavi.

“People have come to me with other ideas, but lingerie is a passion for me, and just like music and acting, I can’t do it unless I put 100% into it,” said Jackson. “There’s something for every woman, and that’s very important to us. I’ve always hated when lingerie is uncomfortable, so the fit and comfort was key.”

“Janet and I wanted to create a collection that empowers women and that makes women feel sexy, flirtatious and provocative,” explained Schiavi. “We wanted to make sure we captured the essence of all Janet’s favorite colors, laces and making sure that we stay true to who she is and what she loves.”

The 14-design line is available in a range of sizes — 32A to 44G, and is mostly satin and lace in rich color combinations such as burgundy and beige, silver and peach, and classic black and white.

Well, now, say ‘Jackson’ and ‘bra’ in one breath, and what do you get? Wardrobe malfunction, of course.

The phrase has become so famous after her ‘mishap’ at the 2004 Superbowl that the Chambers English Dictionary is adding it in its next edition. The Global Language Monitor called it ‘Hollywood’s Top Word or Phrase for Impact on the English language’ in 2004.

Now, it’s just a matter of time before we know if Pleasure Principle is designed to honor the phrase as well. We don’t need to wait till the Superbowl 2009 to find out — the lingerie line will hit the retailers in November.
