Former Playboy pin-up Kendra Wilkinson is pregnant with her second child.

Hugh Hefner's ex is expecting another baby with husband Hank Baskett, according to Us Weekly.

Wilkinson, 28, wed the former American football star in 2009, and they are already parents to son Hank Baskett Iv, three.

The ex-model has been keen to add to her family for a while - she recently told Wetpaint Entertainment, "Hank and I just went on a trip to Big Bear (California) and by the end of the trip, we looked at each other in our eyes, and we said - not drunk - to each other, 'We're ready for baby number two'.

"We have this new love for each other after spending a week together in Big Bear. We have this new energy. We want to bring a new life in together."
