Kendra Wilkinson gave birth to her first child this morning (11.12.09).

The former Playboy Playmate welcomed Hank Baskett IV - her son with American footballer husband Hank Baskett - after undergoing a caesarean section at 12.37am at a hospital in Indianapolis, Indiana.

The new arrival - who was two weeks premature - weighed 9lb 5oz and measured 22 inches long.

The couple issued a statement saying: “We are all healthy and incredibly happy and can’t wait to spend every moment with little Hank.”

Kendra’s ex-boyfriend Playboy founder Hugh Hefner is delighted by the news.

He said: “I send my love to Kendra, Hank and the baby on this memorable day. What a wonderful Christmas present.”

Her friends and fellow former Playmates Holly Madison and Bridget Marquardt also offered their best wishes.

Holly said: “I can’t wait to meet little Hank. I am so excited for Kendra and Hank. They are going to have the best holiday ever!”

Bridget said in an email to E! Online: “This is what I call a Christmas gift that will keep on giving (and taking… lol)! I wish both of them and little Hank Jr. a lifetime of joy and happiness! The only things I wonder… Can I help plan the birthday parties and how will they top this gift next Christmas??? (sic)”
