James Wilkinson of the Daily Mail reports that customers of celebrity-endorsed California cupcake shop Sprinkles have been given paws for thought after footage emerged of a giant rat scurrying across its shelves.

The video, entitled ‘Rat in cupcake store/live Ratatouille’, shows the rogue rodent scampering over empty shelves in the store, which was closed overnight.

On Monday chief marketing officer Jennifer Warner told KTLA 5: ‘We deeply regret that an unfortunate set of circumstances, including a structural malfunction, lead to this incident.’

Sprinkles, which is owned by Cupcake Wars judge Candace Nelson, started in Beverly Hills in 2005. Its Glendale branch opened three years ago. 

According to the Sprinkles website, other celebs that favor the chain include Blake Lively, Katie Holmes, Barbra Streisand and Ryan Seacrest.

These people are celebrities? Hopeless.
