Doogie to Brit -- You Stunt My Growth!

Britney Spears is popwrecka non grata on the CBS sitcom she just cameo'd on – at least according to one of its stars.

In exclusive interview with AP, Neil Patrick Harris says he doesn't want Spears back on "How I Met Your Mother" – nothing personal, he just doesn't think they need recovering celebuwackos on the show for cheap ratings' boosts. "I'm in the minority that our show does not need stunt casting in order to succeed," says Harris.

There were rumors that Spears might make another appearance on the show after her first one -- and producers have reportedly been receptive to the idea.

Rihanna: Cleverly Dumb

Inadvertently or not, like NYC mayor Mike Bloomberg, Rihanna also just confirmed the worst-kept secret in the celebuverse.

"I didn't know!" Rihanna told People at an event. "No one knew!" Knew what, exactly, Rihanna? Apparently she wasn't invited to the wedding or the party – maybe because it had been rumored that she and Jay had gotten together at one point, which both denied.

BeJay were in Houston last night – Beyonce's hometown – but no word yet if there was any confirmation of the nups.
