Chelsea Clinton is on the cover of the forthcoming issue of Elle magazine, which will be available a few days after her mother announces a second run for the White House.

Hillary Rodham Clinton is expected to formally declare her candidacy on Sunday.

The magazine released the cover photo and excerpts of an interview with the younger Clinton late Friday. The former first daughter is now helping to lead her family's foundation.

"When you ask about the importance of having a woman president, absolutely it’s important, for, yes, symbolic reasons — symbols are important; it is important who and what we choose to elevate, and to celebrate," Clinton told the magazine.

"And one of our core values in this country is that we are the land of equal opportunity, but when equal hasn’t yet included gender, there is a fundamental challenge there that, I believe, having our first woman president — whenever that is — will help resolve."

The May issue of the magazine will be available online on April 14 and on newsstands April 21.

The magazine cover features a smiling and stylish Chelsea Clinton, who tells the magazine, "I'm tougher than I look." She discusses being a mother to 7-month-old daughter Charlotte, and the work she shares with her own mom advocating for the advancement of women and girls.

Charlotte is already a much-discussed figure in Hillary Clinton's expected presidential campaign. In the run-up to her bid, Clinton has frequently made the point that every parent wants the best for their child, and a child should not have to be related to a former president or secretary of state to have bright prospects.

"She is just the most remarkable little bubbly, perfect, chunky monkey creature ever," Chelsea Clinton said of her daughter.

Chelsea isn't the only relative of the soon-to-be 2016 candidate to appear on a magazine this week: Bill Clinton, the 42nd president, will be featured on the cover of the May issue of Town & Country:

In an interview with the upper-crust publication, Clinton suggests he will stay mostly behind the scenes in the early phase of his wife's presidential campaign and focus his energies on The Clinton Foundation global charity.

"I think it's important, and Hillary does too, that she go out there as if she's never run for anything before and establish her connection with the voters," he said. "And that my role should primarily be as a backstage adviser to her until we get much, much closer to the election."
