Harper's Bazaar's March boasts a new design, radically simple and minimalistic, making it stand out among the overcrowded covers of fashion magazines.

The oldest fashion magazine in the U.S. features a toned Gwyneth Paltrow in shot by Terry Richardson for two different covers.

While on the issues on newsstands Gwyneth smiles and poses in an Vnes Saint Laurent jumpsuit, home subscribers will see her in Anthony Vaccarello's high-slit black dress, with her face hidden behind a wave of blonde hair. "Gwyneth Revealed," says the tagline on the cover.

Both will go on sale on Feb. 14.

In the candid interview, Paltrow discusses her marriage to Chris Martin.

"I think you do fall in and out of love and you just keep going, and every time you go through a really difficult phase, you rediscover something new and it just gets better," said the 39-year-old actress.

"We've been married for more than eight years now, and we're still into it."

Admitting her marriage is not perfect, Paltrow said the key to a lasting relationship is to "compromise."

"It may not be feminist, but it is about compromise. If you want a family, you have to be a wife," she said.
