Madonna has shot down reports she'll be "dumping" her young sons on ex-husband Guy Ritchie as she tours Europe this summer in a Twitter.com post sent to internet gossip Perez Hilton.

Britain's The Sun reported Madonna will hand the moviemaker custody of Rocco, eight, and adopted David, three, for three months, so she can concentrate on her gigs.

A source told the newspaper, "Guy absolutely dotes on his children and can't wait to have them for a whole three months. He is surprised and pleased that Madonna is being so generous as she has, at times, been impossible."

But the pop superstar is so incensed by the report she fired off at Hilton via Twitter.

She wrote, "What is this rubbish about me dumping my children off for the summer while Im (sic) on tour? They go where i go."
