Reality show star Kendra Wilkinson, who shot to fame as one of Hugh Hefner's three girlfriends on the E! series 'The Girls Next Door,' is pregnant with her second child.

And in our best Maury Povich voice: No, Hef is not the father!

Kendra, who now stars in her own reality show 'Kendra on Top,' is eight weeks along, according to a source who confirmed the news to Us Weekly. Dad is her husband, former NFL star Hank Baskett, whom she wed in June 2009.

Kendra, 28, and Hank, 31, are already parents to their uber adorbs son Hank Baskett IV, who is 3.

Baby No. 2 in the Wilkinson-Baskett family was very much planned, according to the insider close to the situation. "She and Hank have been planning a second baby for a while and they are very excited."

Congrats to Kendra, Hank and lil' Hank on their upcoming bundle o' joy.
