Looks like Katy Perry's granny enjoys the glitz and bling as much as she does.
Katy together with husband Russell Brand have been in Las Vegas to join in Ann Hudson's 90th birthday celebrations.
The couple joined Ann for a meal at the the Strip House steak house in Planet Hollywood's Resort and Casino, before playing the black-jack tables.
Katy later tweeted 'Happy 90th birthday Grandma Hudson. You're the reason why!' she tweeted.
