Mary-Kate and Ashley Olsen have teamed up with author Jessica Weiner to create a new advice column on their Web site.

Weiner admits she was delighted when the Olsen twins asked her to help them create the new daily section, Real Girls, Real Advice, because she’s convinced it will help a lot of tortured teens.

The writer says, “We’re gonna be tackling all the issues that make sense for girls in the world — their bodies are a big one but boys are an even bigger one.”

“A Very Hungry Girl” author Weiner insists she’s the perfect partner for the Olsens in their new venture because, like Mary-Kate, she suffered an eating disorder.
