Guy Ritchie and Madonna

Madonna and Guy Ritchie are set to announce they're divorcing, various reports said.

An official statement is expected to be released some time Wednesday, The New York Post reports. London's The Sun also states an announcement will be issued "imminently."

Speculation on the demise of their nearly eight-year marriage hit a fever pitch in recent months, with reports surfacing of an alleged affair between the singer and New York Yankee Alex Rodriguez.

But now, they "can’t bear to live with the pretence any longer," a source told The Sun.

The two made various attempts to patch up their marriage, but the final straw was when Madonna kicked off her worldwide Sticky and Sweet tour, The Post said, adding that their last-ditch effort included an "intensive kabbalah course in Manhattan."

Madonna, 50, and Ritchie, 40, tied the knot on Dec. 22, 2000 and are parents to three children: 12-year-old Lourdes, Madonna's daughter with Carlos Leon, Rocco, 8, and 3-year-old David.
