JUDE LAW's ex-wife SADIE FROST is fuming after discovering the actor is expecting a fourth child from a fling with a 24-year-old model, according to reports.
Frost is said to be furious with Law for impregnating Samantha Burke during their tryst - because the press attention will confuse the three young children she has with the actor, Rafferty, 12, Iris, eight, and Rudy, six.
A source tells Britain's Daily Express, "It's really hard for the children and they're her main concern. She is deep down furious with Jude - not for having the fling but for being irresponsible - and wants him to pay whatever it takes to keep the family protected from further embarrassment.
"Jude's children, particularly Raffie, are bewildered by the whole thing. They hate seeing their dad in the news and reading about his private life. Sadie is putting on a brave face but deep down is shocked by the whole thing, too."
Burke is seven months pregnant with a baby girl, conceived after her fling with Law while he was shooting upcoming movie Sherlock Holmes in New York.
A spokesperson has confirmed that Law intends to be "a fully supportive part of the child's life".
