Madonna and Guy Ritchie's London pub The Punchbowl is reportedly under investigation for allegedly setting irregular beer prices.
Visitors to the pub, which is located in the Mayfair area of London, have alleged that the establishment is charging increased prices to customers that the staff don't know.
Speaking to The Daily Telegraph, 52-year-old Brian Richardson said: "On Monday I paid £3.50 for a pint, now all of a sudden it's £3.90. I was shocked. I complained to staff. They have got two prices - regulars' prices and non-regulars' prices.
"There is no price list on the wall. I don't mind paying more but it is completely arbitrary. It is not the money, it is the price hike. It is outrageous."
As a result of the customer complaints, Westminster Council is looking into the pub's pricing.
The pub's assistant manager denied there was a policy of different prices and apologised for any errors.
A spokesperson for Trading Standards said: "Given the allegations made the council will be seeking to speak to the licensee."
Ritchie and Madonna spent a reported £2.5m on the pub.
