He was the tattooed and toned hunk that set thousands of female pulses racing when he burst out of jail and onto our screens in the hit U.S. drama Prison Break.
But we suspect Wentworth Miller may find it hard to flutter those hearts today - let alone escape - after letting himself go a tad.
The British-born actor, 37, was snapped out in Los Angeles yesterday and was almost unrecognisable as he went for a hike with a friend.
The sexy shaved head, flat stomach and defining jawline have been replaced by a fuzzy head of hair, a rounder face and a bulging gut.
But Miller didn't appear to be too concerned about his fuller figure as he laughed and joked with his friend, all too aware that the cameras were on him.
The actor, who was brought up in the States but was born in Chipping Norton in Oxfordshire and retains duel citizenship, was dressed casually in a baggy red T-shirt, tracksuit bottoms and trainers.
Miller shot to fame in Prison Break which told the story of two brothers - Lincoln Burrows, played by Dominic Purcell, who was sentenced to death for a crime he didn't commit and Miller's Michael Scofield, who gets himself jailed to save his sibling.
Scofield creates a tattoo - which took five hours to apply each time onto Miller's body - which also had hidden within it, the blueprint of the prison.
At the height of his Prison Break fame, he starred in two Mariah Carey videos for her songs It's Like That and We Belong Together, singles from her 2005 album The Emancipation of Mimi.
But since Prison Break, which ran from 2005 to 2009, Miller has kept a fairly low profile, and has only had a few minor roles.
He appeared in an episode of the hit series Law and Order: Special Victims Unit last year and stars alongside Milla Jovovich and Ali Larter in the upcoming 3D horror film Resident Evil: Afterlife, due out this September.
Last month, he landed a role in upcoming thriller The Mourning Portrait, which is inspired by post-mortem photography that was popular at the end of the 19th century when many people would photograph their recently deceased as a keepsake.
