Throughout her pregnancy Beyonce continued to rock curve-hugging ensembles and sky-high platforms, but now the new mom is enjoying a more laid-back style.

For an outing with Blue Ivy, 4 months, in New York City on Monday the 30-year-old superstar wore baggy black pants, which featured bizarre cartoon characters in lingerie. She paired the wacky bottoms with black loafers and an oversized boyfriend blazer.

She also swapped her usual glamorous hair and makeup for a simple ponytail and pink lip gloss. She did, however, flash her massive 18-carat Lorraine Schwartz diamond ring from hubby Jay-Z. See more photos of Beyonce and Blue Ivy in NYC.

In the past two weeks the "Love on Top" singer has rocked some seriously head-turning outfits including bold Hawaiian-print pants and a neon-pink sweater with a colorful patterned skit.

Although Beyonce is taking a break from work during Blue's first days, she's slated for multiple ventures in 2012: Two new musical projects as well as an appearance in the film One Hit Wonders starring her pal Gwyneth Paltrow plus Cameron Diaz and mom-to-be Reese Witherspoon.
