Heidi Klum: Lou Is "Very Attached To Me Still"

Busy mom of four, Heidi Klum, opened up to Extra about her 3 1/2-month-old daughter Lou Sulola, her new fashion show and her Valentine's Day plans.

The model mom says baby Lou can't get enough of mama these days.

[Lou is] "great," but she doesn't want to leave mama's side. "I mean it's a little bit hard because she's very attached to me still. She doesn't drink from the bottle. That's a little bit of an issue right now!"

And although she's super busy at home, Heidi is participating in The Heart Truth's Red Dress Collection Fashion Show on February 11.

"It's my third year I'm doing this and we get all these amazing women together," the German-born supermodel says. At the show, women wear one-of-a-kind red dresses designed by America's top designers to raise awareness for women's heart health.

And what about her Valentine's Day plans this year? Heidi revealed she will be apart from hubby Seal for the romantic holiday this year. "I'm not going to be with him, I'm going to be in New York for fashion week."

Heidi and Seal are also parents to Johan, 3, Henry, 4, and Leni, 5 ½.
