Heidi Klum is three months pregnant.

The German supermodel is reportedly expecting her third child with her musician husband Seal and is delighted with the news. The pair also have a three-year-old son Henry and a two-year-old son Johan, and raise Heidi's daughter Leni, four, together.

Gossip website E! reports: "A source tells me that Klum, 35, is a little less than four months pregnant."

It has been claimed Heidi is planning to announce her happy news soon.

Rumours about Heidi's pregnancy began circulating when details of couture gowns she will wear on US TV series 'Project Runway' were posted online.

The outfits have reportedly had to be re-designed in order to accommodate her growing tummy.

Heidi is not the only famous face to be surrounded by pregnancy rumours.

Angelina Jolie is said to be two months pregnant with her fourth biological child with partner Brad Pitt.

The actress - who already has daughter Shiloh, two, nine-month-old twins Knox Leon and Vivienne Marcheline and adopted kids Maddox, seven, Pax, five and three-year-old Zahara - was amazed when she found out the happy news.

A source told America's Star magazine: "Yes, Angelina is pregnant. They'd been trying for another baby for months, but it was still a total shock when she found out."
