Sorry, there’ll be no full frontal nudity for LINDSAY LOHAN‘s Playboy celebrity photo shoot when it makes its debut on the January/February 2012 issue. So much for your anticipation, you aren’t getting a single glimpse of Lindsay fully uncovered unless some hackerazzi goes and infiltrates her email account.
2011 (earliest)
A man accused of targeting individuals associated with the entertainment industry by hacking into personal e-mail accounts was arrested today after being charged with a range of cyber-related crimes.
Yes, I know hackerazzi is a plural term (hackerazzo would be the singular form), but that's not how writers — even professional ones — are using the word, so (proud descriptivist that I am), the definition here is singular. H/t to KH for spying this term.
