Kelly Osbourne shared the most beautiful message of love for her son Sidney ❤️ "My son, loving you has been the greatest privilege of my life...You made my world bigger simply by being in it...If I could gather every kiss, every laugh, every time I held you close and every time you reached for me, I would keep them somewhere untouched by time," wrote the media personality, 41. "My beautiful boy. My heart outside my body. My greatest love." 📸 : #kellyosbourne #osbournefamily #motherson
