Katy Perry throws Alice in Wonderland party

Katy Perry has let a small detail slip about her wedding to Russell Brand!

The Teenage Dream singer — who will marry the British comedian later this year — says her ushers will wear skinny jeans — just like the groom.

“The ushers will probably be wearing skinny jeans — just like Russell, really tight,” she says.

Meanwhile, Perry reportedly threw an Alice in Wonderland-themed bridal shower this past Sunday.

The star invited guests to an intimate garden party at a family friend’s house in Los Angeles to celebrate her impending nuptials.

“The party had an Alice in Wonderland theme and only 11 of her closest friends were invited,” a source said.

Guests included her DJ pal Mia Moretti, Markus Molinari and her stylists Logan Horne, Rick Henry and Aaron Light.

Katy recently insisted she and Russell will keep their mouths shut about their relationship when the finally tie the knot.

“People have all these ideas about my relationship and my wedding and there is so much speculation,” she said.

“I’m not a traditional type of person in general but after we get married we’ve decided we’re not going to talk about the relationship.”

Katy Perry’s new album is in stores tommorrow but has been on the net for a week for free download at all the bootleg sites.
