Heidi Klum has vowed to stop having kids just six weeks after the birth of her fourth child. In an interview with Jimmy Kimmel the Victoria's Secret model revealed her new tattoo to mark the arrival of daughter Lou, and said she was considering adding a 'stop sign' at the end.

"The shop is closed. I have tattoos of my children. I just got the star for my little Lou. I was thinking I should put a stop sign there next to it now. Leni, Henry, Johan, Lou and a stop sign right here. The swirly stuff is my husband."

Klum, 36, made her 'no more babies' announcement after having three children in just four years with husband Seal.

While four-year-old Henry was born in September 2005, three-year-old Johan followed in November 2006 and Lou arrived on October 9 this year. Klum also has another daughter, Helene - known as Leni, from a previous relationship with Flavio Briatore.

Despite having given birth just weeks ago, German-born Klum looks in fantastic shape. The catwalk model put her weight loss down to being a busy mother - but said Seal was good at helping out around the house.

"He was in Australia on a tour and he just got back on Saturday. He was right on duty," she laughed. "I said: 'You've been gone for three weeks. I've been getting up by myself for three weeks. Now it's your turn'. "I pre-pumped and I left it in the fridge and said: 'Goodnight everybody'."
