LONDON: Heidi Klum has become a mum for the fourth time - she has given birth to her first daughter with husband Seal.

The supermodel welcomed baby Lou Samuel on Friday morning (09Oct09), according to RadarOnline.com.

The star's rep initially denied Klum had gone into labour on Thursday (08Oct09), but reports suggest the couple wanted to delay the news to prevent any immediate press interest.

The new addition evens up the household - Klum has a daughter with ex Flavio Briatore, and two sons with Seal.
