Jenna Dewan-Tatum has already mastered the art of ultra-cool maternity style.

During a visit to West Hollywood's Plush Beauty Bar Friday, Dec. 21, the stylish pregnant star -- who is now about three months along -- looked effortlessly chic in an all-black ensemble.

Dewan-Tatum, 32, rocked a flowy, cleavage-baring printed frock, a leather blazer, and thigh-high black boots for her afternoon of pampering.

Earlier this week, the American Horror Story actress and husband of three years, Channing Tatum, announced that they're expecting their first child together.

"It was a total surprise," an insider told Us Weekly of the pregnancy, adding that Magic Mike star Tatum, also 32, is planning to take the upcoming year off in order to dote on his expectant wife -- and their new addition.
