Veteran publishing mogul Hugh Hefner has sparked fears for his health after pulling out of a trip to Brazil because of illness.
The 85-year-old Playboy boss took to his page on Thursday (16Feb12) to tell fans he will no longer take part in this year's (12) Carnival celebration in Rio de Janeiro as he is unwell.
He wrote, "I've changed my plans for a trip to Rio for Carnival because of being under the weather."
The tweet came just one day after Hefner revealed his Valentine's Day celebrations on Tuesday (14Feb12) had been "cut short" by an "unexpected anxiety attack".
Hefner has endured a stressful week - his 21-year-old son Marston was arrested on Sunday (12Feb12) after allegedly attacking his Playboy Playmate girlfriend Claire Sinclair at their home in Pasadena, California.
