Washington, Oct 15 Madonna has confessed that breaking up with husband of eight years, Guy Ritchie, was hard for her.

In the cover story of the new Rolling Stone, the Queen of Pop has said that divorcing the 'RocknRolla' director was "challenging . . . I'm very grateful that I had work to do. I may have thrown myself off a building."

Talking about her kids, Madonna, 51, said that it's been "different" with sons Rocco 8, and David, 5, spending time in the UK with their father, 41.

"Life is an adjustment. My sons aren't with me right now, they're with their father, and I'm not very comfortable with the idea of my children not living together," People quoted her as saying.

The boys' sisters are Lourdes, 13 (her father is Carlos Leon, 43) and Mercy, 3, adopted by Madonna after the divorce. (ANI)
