Gwyneth Paltrow is beautiful in black on the cover of the March issue of Harper’s Bazaar. Inside, the Oscar-winner talks about family and why she and Coldplay frontman Chris Martin are still happily married.

“I think you do fall in and out of love and you just keep going,” the actress says. ”Every time you go through a really difficult phase, you rediscover something new and it just gets better. We’ve been married for more than eight years now, and we’re still into it.”
