The blonde star acted as the Maid of Honour at her Pussycat Dolls bandmate's nuptials to Max Rogers on February 22 and Ashley couldn't hold back the tears when they began to walk down the aisle.
Talking on British chat show 'Lorraine', she said: ''Kimberly was the first one out of all of us. Kim and I were friends even before we were in the Dolls, and so she's my sister.

Following the ceremony Ashley, 32, wished the newlyweds well and hopes they have a fairy tale ending.
She wrote on Twitter: ''Congrats to the newly married couple @max_rogers @KimberlyKWyatt !! Was truly a fairy tale day. Here's to happily ever after (sic)''
