In an interview which will air on “The Ralphie Radio Show” August 22, Selena Gomez shot down a pair of rumors about her alleged involvement in a new “Sex and the City” TV series and a Britney Spears tribute planned for the 2011 MTV Video Music Awards.

The interesting thing is that Gomez calls herself both a fan of the TV show and the pop star. Although, her youth (and therefore, her mother) made watching the former a limited experience until she got older.

“I wasn’t allowed (to watch) when I was younger, so I kind of missed a lot,” Gomez said. “But I used to watch a couple episodes.”

The Disney star says the rumor of her playing Charlotte in the planned series is just that, a rumor.

“I haven’t been approached,” she revealed. “It would certainly be an honor, but I haven’t been approached.”

Gomez probably also thinks participating in a Britney Spears tribute is an honor. After all, the starlet pays homage to Britney every evening on the “We Own the Night” tour, performing and dancing to a medley of Spears tracks. During her show, Gomez reveals the first ever concert she attended was a Britney show at age 11.

“No. That would be cool too, but no,” she responded when I brought up the reports of her teaming up with Demi Lovato, Miley Cyrus, Katy Perry, and possibly others at the VMAs next Sunday.

Speaking of Lovato, Gomez did talk about her friend’s upcoming birthday and how she’ll spend it.

“She’s having a big birthday party, and unfortunately I have a show, so I can’t go,” Gomez said. “But she’s going to have the best time and she’s going to go with one of her other really good friends. It’s going to be a good birthday.”

The full conversation with Gomez airs Monday evening on “The Ralphie Radio Show.”
