Kendra Wilkinson was shocked to discover her son can speak Spanish.

The 'Kendra On Top' star and husband Hank Baskett are now planning to take classes after being impressed with how easily two-year-old Hank Jr. has picked up phrases from his nanny, who speaks to him in her first language.

Kendra told People: ''We were at a friend's house for dinner and all of a sudden out of nowhere he speaks this sentence in Spanish. He said, 'I would like more milk, please.'

''I never expected it, and he's doing so good. I was so caught off-guard. I thought he was speaking baby. Now Hank and I are going to have to learn Spanish, but it's a good thing.''

Kendra recently admitted she and Hank want to have another child - and joked she might even conceive on her new reality TV show 'Kendra On Top'.

Asked if she is planning on having another child, she said: ''That's a true true thing that's happening in my life right now ... Do we want to have baby number two right now?

''You'll get a chance to go through that with me. I want to figure it out and bring my fans through that process. Who knows you might even see me on top of Hank and get pregnant!''
