Pop diva Madonna is struggling to adjust to life as the mother of two adolescents, her 12-year-old son Rocco has already started growing facial hair and is chasing after girls.

The Material Girl has four kids, Lourdes, Rocco, David, and Mercy and she insists the toughest part of parenting is watching her two eldest kids' transition into adulthood and display less of an interest in hanging out at home, reported a magazine.

"My daughter (Lourdes) just got an iPhone, she is 16 and now she has stopped talking to me. It's kind of uncomfortable; she's still my little girl, but she's also a woman," Madonna said.

Rocco, who performed as a back-up dancer on the pop star's recent MDNA tour, will turn 13 in August and Madonna insists he's going through a number of changes as well. "He's a foot taller, he's getting facial hair and he’s looking at girls' butts. It's terrible!"

Lourdes is Madonna's daughter with ex-lover Carlos Leon, while filmmaker Guy Ritchie is Rocco's father. David and Mercy are Madonna's adopted children from Malawi.
