It was only a month ago that fans were wondering when the first images of new mom Beyoncé might hit the Net. On Monday night, those questions were answered. Just four weeks after giving birth to daughter Blue Ivy, B was back on the scene to celebrate hubby Jay-Z's first show at Carnegie Hall.

Wearing a form-fitting red dress, she hit up a post-show party held at Jay's 40/40 Club in New York City. And while Beyoncé could have premiered her post-baby body on a splashy red carpet, celebrity experts note that the more understated move is very B.

"It's perfect for this private couple. She didn't make a big deal walking a red carpet at an award show or posing on the cover of a magazine," Huffington Post celebrity columnist Rob Shuter told MTV News on Tuesday (February 7). "Beyoncé made it as low-key an event as possible and at the same time plugged her husband's club."

For the appearance, Beyoncé was decked out in a fiery-red Temperley London dress, Christian Louboutin heels and an Alexander McQueen clutch. While that may sound very glam, another expert was surprised by just how modest the look actually was.

"Beyoncé looks amazing in her first post-baby appearance. Even thought it made sense for her to make her debut last night to show her support for her husband and the charity his concert benefited, her outfit was fairly simple," celebrity editor David Caplan said.

"I expected her to make her post-baby debut at a really glitzy event or awards show, like maybe the Grammys, in a gorgeous gown and really steal the show. But clearly she wanted to be seen, since she even posted photos of herself right away on her website, which stars don't typically do — they'll just let the media pick up and run the photos."

So, will B and Jay play it just as cool when it comes to releasing the first shot of their newborn? "It will be a [paparazzi] shot taken on the beach or when the couple is on vacation," Shuter predicted. "They won't reveal the baby to get a [magazine] cover like Bethenny [Frankel] or those other reality stars."

Caplan also proposed that a baby photo will probably leak. "As for when will we see baby Blue, I wouldn't be surprised if some sort of grainy-looking paparazzi photo emerges," he said. "Those photographers are very crafty, even if Beyoncé and Jay-Z think they're doing all they can to keep Blue away from photographers. But ultimately, I think you can expect to see her baby photos in a magazine pictorial, and that will be Blue's introduction to the world. That's the real reveal people want to see."
