Kendra Wilkinson is trying for another baby.

The former Playboy model - who gave birth to son Hank Baskett IV in December - is said to be keen to add to her brood as she believes it will help solve the reported problems in her marriage to American footballer Hank Baskett.

The couple’s 11-month union is said to be on the rocks following the emergence of a sex tape Kendra made before she was famous and the 24-year-old blonde hopes another child will give them something positive to focus on.

A source told Life & Style magazine: “They’ve been trying for a second child for a while. And Kendra hopes it will happen sooner rather than later. Kendra knows she upset Hank over all this sex tape stuff, and she wants it all to go away. Focusing on another baby would help.

“There was some tension, but they managed to get over their problems and focus on the baby. At the end of the day, Kendra’s main concern is keeping her family intact, and a new child could only help.”

Kendra - whose ex-boyfriend is Hugh Hefner - recently revealed she is keen to find some friends for little Hank as he currently only has the family pets for company.

She said: “He’s starting to lift his head and really look around…He’s so smart. He mimics.

“He’s starting to notice the dogs; he’s like ‘What are those?’ I really want to start to find other babies he can be around. I don’t want him thinking that he’s a dog.”
