Britney Spears says son Jayden, 18, is a "genius" after he plays the piano for her, adding that she "can't believe he's mine." The singer shares her sons, Jayden and Sean, 19, with ex Kevin Federline.

In the second video, Jayden, now wearing dark shades indoors, walks around mumbling as Britney screams, “Well that was really good! My son just played! Oh my God! I felt it in my bones, and my heart, and my lungs, and my a–, and my throat and my…,” as Jayden appears to complete the thought with “my d–k.”

Pop star Britney Spears may finally be ready to make a career comeback, and it’s all thanks to her son, Jayden. Although her “The Woman In Me” memoir is being turned into a biopic, the “Toxic” singer hasn’t released new music in years.
