A pregnant Beyoncé Knowles hit the NYC streets today in a daring gray minidress and a towering bun with bangs. The singer has been out and about in the Big Apple almost every day lately, and last night, she and Jay-Z spent the evening at Frames Bowling Lounge with friends including La La and Carmelo Anthony. B has a lot to celebrate these days in both her personal and professional life. She recently released two new videos, "Love on Top" and "Countdown," from her album 4. Beyoncé also will launch a maternity line, and during her pregnancy, she's kept her own style as sexy as ever in a rotating wardrobe of short dresses and stilettos. Jay-Z and Beyoncé's child is due in February, and yesterday, her mother, Tina Knowles, said they know the gender of the baby! Despite it, the couple are keeping the sex of their firstborn under wraps for now.
