Kendra Wilkinson celebrates son's birthday

Kendra Wilkinson has celebrated her son's first birthday.

The Kendra star and her NFL player husband Hank Baskett welcomed son Hank Baskett IV, their first child together, on December 11, 2009.

Writing on her Twitter account over the weekend, she said: "I can't believe my baby is 1 today!!!!! I'm such a proud mama! Happy birthday lil hank! I love you SO SO much!

"Such an amazing day!!! thank you all for the sweet birthday wishes for baby hank! luv u all! goodnight! (sic)"

The reality star previously told Digital Spy that she was planning a "huge" party to celebrate the birthday, joking that she will always remember the big day even if her son is too young.

"[My husband has] been doing so much. He's the one who actually got everything ready," she said. "We want to make sure this is the perfect first birthday. He told me he went a little overboard but there's no such thing!"

Kendra airs on Sundays at 10pm on E! Entertainment Television.
