Pop star Katy Perry walked down the aisle at the weekend (05-06May12) - to serve as her sister's bridesmaid.
The I Kissed a Girl hitmaker, who split from estranged husband Russell Brand late last year (11), 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!"
