[P]art of my family is out in LA doing the tourist thing. They went on the WB studio tour yesterday and saw Britney sitting outside a studio where she was working on a routine with the Pussy Cat Dolls.

But today, MTV News is reporting that the PCD video has been completed and Britney’s cameo was cut for the final version:

Britney Spears may have looked “hot and blond” in the cameo she filmed for the Pussycat Dolls’ new video, “When I Grow Up” — which will premiere on FNMTV Friday night — but we may never know just how hot and blond. Spears, who filmed a bit part in the video for the first single from the Dolls’ upcoming album last week in Los Angeles, was edited out of the final cut of the clip. A spokesperson for the Dolls could not be reached for comment on why Spears was not included in the video. The group’s members did not elaborate on the edit during the taping of “FNMTV” Thursday night in Los Angeles.

Extra TV has posted a short clip of the music vid HERE for viewing and also confirm that Britney didn’t make the final cut of the music video:

Reports claim that Britney Spears makes a cameo in the video, but “Extra” has seen the finished product — and we were unable to spot Ms. Brit!

Either PCD is dumb as hell for not using Brit’s cameo … OR they’re saving her for the remixed or alt. version of the vid. The song is growing on me like crazy (blame it on the “ha ha ha ha” part) and I was really looking forward to seeing Brit Brit in the vid. I hope we will get to see her cameo at some point.
