Seal angry about Heidi Klum`s date?

London: Soul singer Seal is reportedly furious over claims that his estranged wife Heidi Klum is dating `Germany`s Next Top Model` judge Thomas Hayo. The former couple - who have children Leni, seven, Henry, six, Johan, five, and two-year-old Lou - ended their seven-year marriage in January and started divorce proceedings earlier this month, reported Contactmusic. But Seal, 49, is said to be less-than-pleased about pictures which show Klum enjoying a romantic picnic date with Hayo. "Seal`s been in a terrible mood for weeks and this has really set him off. He says they agreed not to start dating until the divorce was finalised," a source said. However, Klum, 38, insists she and Hayo are just friends. Following the announcement of the couple`s separation, Seal has said the pair had "grown apart", but insisted he still "very much loved" Klum. PTI
