*With Beyonce a first-time mom-to-be, and her sister Solange having already been-there-done-that, Bey is looking to her younger sibling for all kinds of pregnancy and parenting advice, including what to wear while expecting.

“I go straight to net-a-porter.com and I copy and paste URLs and send them her way,” Solange, mom to 6½-year-old son Daniel Juelz, told InStyle.com recently. “We also go shopping together. She’s getting bigger. It’s so fun when you’re actually really showing and you’re able to showcase that.”

So has pending motherhood changed Beyoncé’s signature sexy look at all?

“Her style is the same,” Solange assured. “Wonderfully glamorous.”
