Heidi Klum 's reps confirm that she gave birth to a baby girl on Friday  and they named her Lou Samuel! Lou joins big brothers Johan and Henry as well as sister Leni. Heidi recently started the process  of legally changing her name to Samuel as well. Heidi has been out and about throughout her pregnancy so we've been watching her baby bump the whole time. Over the weekend her adorable kids checked out the pumpkin patch  while mom and dad were taking care of the new addition. We're so excited for one of our favorite families in Hollywood. Congrats to Heidi, Seal and their growing family!
