Taking the high road!

Sharon Stone took to Facebook on Thursday, July 13 to pen a heartfelt response to her pal Madonna, who branded the 59-year-old actress “horribly mediocre” in a recently leaked letter that was written in the early 90s.

“First, I think it’s absurd that anyone is publishing your private letters. Therefore; I publish publicly,” Sharon wrote alongside a photo of herself and Her Madgesty, 58, posing together on a red carpet. “Know that I am your friend. I have wished to be a rock star in some private moments… [and] have felt as mediocre as you described.”

The Basic Instinct star added, “We know, as only those who have survived so long that owning our own mediocrity is the only way to own our own strengths; to become all that we both have become. I love and adore you; won’t be pitted against you by any invasion of our personal journeys.”

In Madonna’s letter — which was obtained by Radar Online — the pop superstar not only slammed Sharon, but also criticized the late Whitney Houston’s singing ability in comparison to her own “original and unique” talent.

“I have made so many people angry that I’m being punished and basically being made to be quiet and sit in a corner while other less interesting and exciting people are reaping the benefits of the road I’ve paid,” the “Living for Love” singer wrote in a handwritten note addressed to “J.”

The letter continued, “It’s so unequivicably [sic] frustrating to read that Whitney Houston has the music career I wish I had and Sharon Stone has the film career I’ll never have. Not because I want to be these women because I’d rather die but they’re so horribly mediocre and they’re always being held up as paragons of virtue and some sort of measuring stick to humiliate me.”

Madonna has yet to publicly address Sharon’s post. The Grammy-winning musician’s former art consultant, Darlene Lutz, gave the letter to the Gotta Have Rock and Roll auction house, where it will be auctioned offed on Wednesday, July 19.
