Katy Perry walks down the aisle again - as sister's bridesmaid

Pop star Katy Perry walked down the aisle at the weekend - to serve as her sister's bridesmaid.

The I Kissed a Girl hitmaker, who split from estranged husband Russell Brand late last year, watched with pride as her sibling Angela exchanged vows with her partner.

In a series of posts on her Twitter.com page, Perry writes, "Shout out to my big sissy who sealed the deal this wknd & a lovely thank u to Amsale for our gorge bridesmaid dresses. We felt like fairies! I have danish in laws now!"
