Two weeks ago, the anti-abortion group Center for Medical Progress began releasing undercover videos they say shows Planned Parenthood employees discussing the sale of fetal body parts for research, which sparked national controversy.
Planned Parenthood, which has provided medical services for reproductive and other women's health issues, including abortions, for almost 100 years, has denied any wrongdoing and says the footage is edited.
"Planned Parenthood was the only organization in my town growing up available to teach young girls @ sexual responsibility," the 35-year-old "Just Give Me One Reason" singer-songwriter, a married mother of daughter Willow Hart, 4, said on Twitter on Wednesday. "I stand with PP."

Donated human fetal tissue may be used for research under federal law. Profiting from selling any is illegal.
"The allegation that Planned Parenthood profits in any way from tissue donation is not true," Planned Parenthood President Cecile Richards said in a statement.
Eric Ferrero, the group's vice president of communications, said the organization helps parents who want to donate tissue for scientific research and obtains "full, appropriate consent" "under the highest ethical and legal standards."
"There is no financial benefit for tissue donation for either the patient or for Planned Parenthood," she added. "In some instances, actual costs, such as the cost to transport tissue to leading research centers, are reimbursed, which is standard across the medical field."
Republicans, including presidential candidate Rand Paul, want the government to cut the more than $500 million in federal funding that the group receives annually. Currently, none of the money can be used for abortions, which constituted 3 percent of the organization's medical services in 2014.
"Do these Rep. hopefuls plan on visiting every town in America handing out pamphlets, hugs, life saving info + screening?!" Pink tweeted. "What's their plan?"
She also replied to a fan's comment.
"@Pink I like the idea that someone might support people when they need help, but I don't like PP selling baby parts for cash," the person wrote.
"Are you for real?" Pink asked. "Did you hear that on Fox News?"
