Hamrick recently spoke about the age gap, revealing that she "doesn't think about it."

"Everyone’s going to have their opinion," she said in an interview with The Times. "If you think about others’ opinions, no matter where you are in life, you’re going to have a problem and you’re going to analyse it."

“I put the blinders on. Am I happy? Yes. Are the people in my life happy? Yes. Am I hurting anyone? No. OK, they can mind their own business.”

Through the interview, Hamrick shared a bit about her personal life, including her and Jagger's son Deveraux, and their blended family, which includes Jagger's exes, Bianca Jagger and Jerry Hall , and his seven children. She also revealed that, as a former ballerina dancer, she and Jagger share an understanding when it comes to performance. “Mick is the perfect balance,” she said. “He’s not a ballet dancer but he is a dancer and a performer, and we understand each other’s worlds, yet we’re not in each other’s worlds.”
