Wikipedia
Holy Moly, often known as "HM", was an entertainment website based in the UK and had similarities to Popbitch, Anorak and B3ta. It published (often mocking) gossip items related to celebrities, notably Amy Winehouse, Sienna Miller, Britney Spears, Tom Cruise and Paris Hilton. The website's scoops were often copied in the gossip pages of British tabloids such as The Sun the Daily Mirror and the Daily Star. Sometimes Holy Moly would announce news before tabloids, for example, Madonna's divorce from Guy Ritchie four months before The Sun's front page 'exclusive'..
Its content was usually extremely scathing, for example a typical news item reads, "Lady Gaga covers up her face with gimp mask, improves".
The phrase "Holy Moly" is an exclamation of surprise that dates from at least 1892.
The MediaGuardian website claims that the gossip was "supplied by an army of around 100 industry insiders". In November 2007, Sky News' James Silver interviewed Mr. Holy Moly – the interview revealed that he had started the website on a secret laptop whilst working at Sky News. Recently, he has appeared frequently on BBC Radio Five Live's Richard Bacon show as the presenter's friend and has maintained his personal anonymity, albeit revealing a distinctly Derbyshire accent. February 2008, he appeared on Channel 4's chat show The Richard & Judy Show, attacking photos of celebrities such as Britney Spears, Amy Winehouse and Heather Mills-McCartney and declaring that these paparazzi are damaging the business.
On 10 March 2015, it was announced that Holy Moly was to close down.
