Beyoncé, Gisele Bündchen, and Mariah Carey Among Top 10 Power Moms

No single ladies here! Just in time for Mother's Day, Working Mother released its list of the 50 Most Powerful Moms of 2013. While a few, slightly less famous faces snapped up the first four spots, fan faves Beyoncé, Gisele Bündchen, and Mariah Carey all made the top 10.

Beyoncé -- whose job description is aptly listed as "Singer, Actress, Mogul" -- came in fifth. Labeled as "arguably the hardest working mom in show biz," (which may or may not have rubbed Mariah the wrong way), Mrs. Carter landed this spot based on her achievements since the birth of her daughter Blue Ivy last year.

Among the highlights: singing at Obama's second inauguration, headlining the halftime show at the Super Bowl, unveiling a self-produced HBO documentary, releasing a new album, and starting a world tour, which is fueled by an eye-popping $50 million Pepsi endorsement deal. Kind of makes you feel unaccomplished, right?

Gliding into eighth place is "Supermodel/ Environmentalist" Gisele, who happens to be the richest supermodel in the world (and mother of three, and wife of superstar quarterback Tom Brady).

Citing her "endless" list of modeling jobs, business ventures, and endorsements, the powers-that-be also were impressed by the beauty's post as ambassador for the U.N. Environmental Program which involved her planting trees in Brazil and speaking about sustainable energy in Kenya. Oh, she also got props for riding an ATV with her newborn daughter strapped on in a baby carrier. Hmm.

Rounding out the top 10 is Mariah Carey herself, who's listed as working in the fields of entertainment and (for some inexplicable reason) literature.

Married to hubby Nick Cannon with whom she shares two-year-old twins, the mogul gets a shout out for selling more than 100 million albums worldwide, earning $18 million for her work as a judge on "American Idol," being a critically acclaimed actress (for "Precious," not "Sparkle"), and, last but not least, creating a serious fragrance empire. (She's got 12 brands under Elizabeth Arden, in case you lost count.) She also got a shout out for terrorizing Nicki Minaj during filming. Okay, that last part's made up, but don't you wish it weren't?

Burberry Group CEO Angela Ahrendts led the list at no. 1, but several other stars ranked just fine. Tina Fey, Katie Couric, and "The Hunger Games" author Suzanne Collins all helped to round out the top 20, while Angelina Jolie and Jennifer Lopez sat solidly at 27th and 31st, respectively.
