Meghan McCain blasted Prince Harry's naked Las Vegas pictures as a "rookie move," saying she never allows cell phones or video cameras around when she parties it up in hotel rooms and telling the rowdy royal to grow up.

In a video for her "Stark Raving Meghan" segment on the Daily Beast's website, which can also be viewed below, the daughter of former Republican presidential nominee and U.S. Sen. John McCain, R-Ariz., said the supposedly nude photos of Harry embracing naked women in his room at the Wynn should have never come out.

"My friend, this is a rookie, rookie move," Meghan McCain says into the camera. "Every time I throw a party in my apartment or in a hotel room in Las Vegas ... cell phones and cameras are confiscated at the door. This is my big rule: There are no cell phones, no camera phones allowed in my personal space."

Harry and McCain are both 27, but she said Harry should grow up amid his nude antics at the Wynn Las Vegas that embarrassed Britain's royal family.

"I feel like I'm past the age of playing strip poker and being nude in public places," she said. "I mean, I'm not that old but I'm too old for that."

Addressing Harry directly, McCain continued, "part of me thinks it cool that you're still living your life and partying. The other part of me is glad that this wasn't [America's] first family and our first kids embarrassing our country." McCain was referring to Malia, 14, and Sasha, 11, the daughters of President Barack Obama.

McCain added that she believes she's living in the best country in the world, offering Prince Harry's behavior and the upcoming marriage of Canadian singers Avril Lavigne and Chad Kroeger as evidence.

"Right now we got Avril Lavigne and Chad Kroeger are getting married, so Canada, you're out," she said. "And now we got Prince Harry. Britain, you're out. America's the greatest country in the world."
