“American Idol” 2006 contestant Princess P is becoming a mommy.

Paris Bennett is expecting a baby girl in October and will be 20 when mommyhood arrives.

“This makes five generations,” an overjoyed Jamecia Bennett, told me Thursday.

Jamecia, who like her daughter and mother is a singer, is absolutely over the moon about being a first-time grandmother.

“I’m proud of how she did it. I was 16 when I got pregnant,” said Jamecia.

Paris’ great-grandmother is Shirley T. Bennett, 75, of Rockford, Ill.; her grandmother Ann Nesby, a gospel and R&B powerhouse, who lives in Atlanta, was with the Sounds of Blackness.

Who’s the daddy? “He chooses not to be in the public eye,” said Jamecia. “I respect that.” What does he do for a living? “I can’t tell,” she said.

“She has a ring,” said Jamecia, who’s hopeful that she’ll be planning a wedding for Paris.

The planning for an August baby shower is already underway. A few celebrities may fly into town for the show, including Queen Latifah.

Latifah has made it clear that she plans to spoil this baby with gifts and that she won’t be stopped. You’re the princess but I’m the queen, Jamecia said Latifah told Paris.

National magazines have been calling looking for baby info, but Jamecia said she’s played it cool. “We tend to stay out of the media,” Jamecia said. “The only person we let know [personal] things is you.”

Um, then why did I have to hear about this pregnancy elsewhere?

MediaTakeOut.com published photos of Paris and her grandmother. The website was not sure whether the photos confirmed web gossip about Paris being pregnant or whether she needs “to be pushing back from the table just a tad bit.”

Jamecia said she’s be surprised how tame, and relatively kind, MediaTakeOut has been. “You know they can be something else,” said Jamecia.
