Supermodel Claudia Schiffer (search) gave birth to a baby girl in London Thursday.

"I would like to thank my beautiful wife Claudia for giving me an equally beautiful daughter, a little sister for Caspar," said film director Matthew Vaughn (search), who married Schiffer two years ago.

The baby weighed 7 pounds 2 ounces (3.24 kilograms) and mother and daughter were reported to be doing well. The couple did not announce her name.

The newborn, delivered at London's Portland Hospital, is the second child for Schiffer and Vaughn, who married two years ago. They have a 22-month-old son, Caspar.
