Beyonce in full-on sexy/mommy mode

From the looks of it, Beyonce is in full sexy/mommy mode.

I'm sure you've seen the 31-year-old singer's Superbowl leather and lace onesie by New York-based designer, Rubin Singer.  It was sharp. Singer is a favorite of starlets who gravitate toward the sleek and the daring, but he's relatively unknown to the rest of us. He must have had a very busy January as he also designed fellow Destiny's Child Kelly Rowland and Michelle Williams' outfits, plus the dozens of on-stage dancers.

Beyonce's sizzling one-piece was a mixed metaphor at its fashion best: part sexy, part demure. It featured a deep-V - but not a bit of cleavage was visible. The slight peplum detailing was fashioned from lace - you can't get more lady like than that. But it was black lace, scandalous! She wore flesh-colored fishnet stockings with booties - not pumps, but booties. The fingerless gloves added a homeless-chic vibe.  And the knee-high socks were Catholic school naughty. It was all so perfectly good girl meets bad girl. (I hope the costume designers on the set of HBO's True Blood took good notes.)

There is other evidence of Bey's grown-up sexy emerging.

She's on the February cover of GQ magazine in a look that shows more than a hint of bootie and boobs.  On the 16th of this month, HBO will air a Bey documentary,  Life is but a Dream. In the trailer, Beyonce talks about how she longs to share more about herself, but she can't. She wants to stay current, she says. But  you can tell she has a tough time telling her whole truth. She can't risk opening the floodgates of criticism. It's got to be a lot of pressure  keeping such a picture-perfect image and her hip hop czar husband, Jay-Z, happy. (You know he must have felt like a king when she was on stage.)

Beyonce has already weathered a bit of criticism from Sunday's performance, with all of that writhing on the floor. And why so much crotch?

But I think Beyonce, like the zillions of other entertainers before her who found themselves evolving into full blown womenhood before our eyes, use their clothes to speak for them when they just can't.

So on Sunday night  when she had American men's full attention, she picked an outfit that said:

You can't keep me in a box. I may be a mom. I may have been on the scene for a while, but I'm still sexy and still relevant.  I may not be able to tell you everything, I want to, but I will not be ignored!

The most important message: If you think I'm inappropriate, that's your problem not mine.

And then the lights went out.
