And while they waited for the pop diva to arrive, they grooved to the Grammy Award-winner's new chart-topping CD, "B'Day."
Although Beyonce and mom Tina officially stopped by to introduce the nation's first House of Dereon in-store boutique, fashion didn't seem foremost on the minds of the 2,000 fans who thronged Macy's first floor and atrium balconies to glimpse the star.
It was all about showing love for their girl, greeting her with popping flashes, huge smiles and ear-piercing, Beatlesque screams.
"This is CRAZY," a ponytail-wearing Beyonce told the young crowd after taking the stage alongside her Dereon-designing mom. "Hello, everybody!"With a clothing line offering everything from stage-ready bustier gowns to trend-right skinny jeans and wrapped-and-tucked jersey dresses, the Knowleses spent two years creating their latest venture.
"It was important we didn't just put my name on something I wasn't involved with or wasn't proud of," Beyonce told interviewer Bobbie Thomas, co-host of E! Entertainment Television's "Fashion Police," and her shrieking fans.
Just how does a 25-year-old juggle a brand-new fashion line, best-selling CD, budding film career and onstage performances like tonight's at Macy's Glamorama?
"It's tough at times, making sure I balance myself and have time to relax and recharge and come up with new ideas," Beyonce admitted. "It is possible to do. I'm doing it now -- at least the best I can."
And her Chicago fans appreciate her keeping it real.
"I'm not obsessed," claimed University of Chicago student John Frame, 22. "It's not the trivial things, but she really respects her music, respects her fans, takes time to deliver."
