Michael Clarke Duncan, the “Green Mile” star who is practically impossible to describe without using the phrase gentle giant, died Monday after a July 13 heart attack from which he never fully recovered. The actor — who also appeared in such films as “Sin City,” “The Whole Nine Yards” and “Daredevil” — was 54 years old. A spokesman for the L.A. coroner’s office told the Los Angeles Times that his death will not be investigated because of the former bodyguard’s preexisting heart troubles.

The loss of Duncan, who had planned to marry fiancee and former “Apprentice” contestant Omarosa Manigault in January, according to TMZ, was mourned by a variety of Hollywood stars, including Tom Hanks, “Green Mile” director Frank Darabont and The Rock.

“He was the treasure we all discovered on the set of ‘The Green Mile.’ He was magic,” Hanks said of his co-star in a statement.

“Michael was the gentlest of souls — an exemplar of decency, integrity and kindness,” Darabont said in a statement of his own.

The Rock, who starred with Duncan in “The Scorpion King,” added to the chorus of tweets that paid tribute to the big man with the generous soul. (Associated Press; E! Online)

Prince Harry has made his first public appearance since the Las Vegas strip billiards debacle. He appeared Monday at London’s WellChild Awards, a ceremony that honors brave, critically ill children and those who work with them. A 6-year-old leukemia patient named Alex Logan had promised on Britain’s ITV network that he would say, “I’m glad you’ve got your clothes on, Harry,” when he met the Prince, but Harry managed to play some defense in that regard. “You keep looking up at your mum,” he joked with the boy, according to the Daily Mail. “It looks like you’re dying to say something, but you’re worried she’ll tell you off. I heard you were on ITV earlier and you said something cheeky — but let’s not talk about that here.” For the record, the adorable pictures that accompany this story are the kind of photos in which we much prefer to see Harry.

— Heidi Klum released a statement to People magazine stating that she and Seal have moved on since their separation was announced in January. “I cherish all of the great memories Seal and I created together over the years. . . . Our separation was based on issues between the two of us,” Klum said. The statement came after Seal confirmed to TMZ that his soon-to-be ex-wife is romantically involved with her bodyguard, Martin Kirsten, adding, “I would’ve thought that Heidi would have shown a little more class and at least waited until we separated first before deciding to fornicate with the help, as it were.” Seal later said he did not mean to imply that Klum was unfaithful during their marriage, even though that sounds like what he was saying in that sentence, right around the part where he used the word fornicate.
