10. Donnie Wahlberg–The Sixth Sense
Donnie is best known for her singing in the famous boyband from the 80’s and 90’s, The New Kids On The Block. He has dabbled in acting over the years most recently with the hit CBS show with Tom Selleck, called Blue Bloods in which he plays a police detective. Yet, back in 1998 he had a bit part in the thriller starring Bruce Willis called The Sixth Sense. He played at the very beginning of the movie a suicidal patient of Willis who got very thin due to anorexia and other psychological problems. It was truly haunting to see Walhberg at such a low weight and it’s said he lost 40 pound off his already fit shape. Maybe his new wife, Jenny McCarthy will appreciate how fit he is now with his six pack abs about to embark on a New Kids Reunion Tour. Not bad for a guy in his late 40’s.
