Since giving birth to daughter Blue Ivy almost four months ago, Beyonce has worn everything from sexy curve-hugging dresses to unexpected accessories including hipster-friendly sunglasses, loafers and knit caps.

And on Wednesday the new mom, 30, showed off her legs in a pair of skin-revealing black footless tights in New York City. She wore the unique stockings with a black cardigan, blue tee shirt, black hat and $760 Isabel Marant high-top sneakers.

The "Love On Top" singer hasn't let parenthood slow her down. On Monday she joined husband Jay-Z to watch the New Jersey Nets take on the Miami Heat at Newark's Prudential Center Monday alongside a very special guest: the couple's 7-year-old nephew Julez Smith. (Mom is Beyonce's sister, Solange Knowles.)

Bey and Jay also packed on the PDA while sitting coursed at a New York Knicks game in the Big Apple Friday. Beyonce wore shades and a black fedora, but the couple -- who celebrated their fourth wedding anniversary April 4 -- weren't shy with their affection during the basketball game. The rapper lovingly caressed his wife's face in front of the cameras.
