Simon Cowell from America's Got Talent has had a physical transformation that's raised eyebrows, and we're here to show AGT fans just how much he's changed over the years. Most viewers were introduced to Simon when he was part of the American Idol judging panel. Back then, Simon was known for his v-necked t-shirts, boot-cut jeans, signature thatch of dark hair, brutal honesty, and wicked wit. Everyone ages and the natural aging process is surely part of the reason why Simon, 61, has a dramatically different look these days. However, a lot of people have speculated that plastic surgery is the primary reason for Simon's current look. There are even AGT and American Idol fans who speculate that Simon (who recently pranked Sofia Vergara on AGT) had botched cosmetic procedures.

Simon is English and grew up in a wealthy family. He was born on October 7, 1959, under the zodiac sign, Libra. Simon's mother and father chose to send him to boarding school, which he hated. He was eventually suspended and stopped attending school entirely at the young age of 16. During his childhood, he lived in Elstree, which was known for its television and film studio. Plenty of TV and film luminaries lived in the Hertfordshire village. Simon was destined to join their ranks by becoming a successful music executive who reigns on reality TV. Since the bright and acerbic reality star has held the public's interest for so long, it's interesting to look at his physical transformation through the years.

Simon Cowell During His American Idol Heydey

In the photo above, taken during the American Idol heydey, Simon is glowing and looking supremely content. This was a time when he and his fellow American Idol judges (including Randy Jackson, who is focusing on his health these days) were enjoying incredible success on the singing competition show. American Idol was a sensation in its earlier seasons, in large part because Simon was willing to tell it like it is. However, all of the judges brought their own attributes to the table. Audiences were riveted by the best and worst auditions, the commentary from the judging panel, and the thrill of watching great talents like Kelly Clarkson gain confidence through the episodes. In this photo, Simon was tanned and decked out in a form-fitting shirt. He was really at the height of his powers. See Simon during season 1 in the clip below, which features Kelly Clarkson's iconic audition:

Sporting Graying Locks On AGT

In the shot above, which was posted to the official America's Got Talent Instagram (@agt) in May of this year, Simon rocked a silver fox look. While he still has plenty of dark strands, the very short sides of his hair were gray and so was some of his stubble. It's not the fairly subtle change to Simon's hair color that is getting attention from fans and the press. People are more interested in his weight loss and his possible plastic surgery. Simon has been quite open about getting Botox in the past but has denied getting other work done. According to The Sun, Simon embraced a vegan diet at age 59, which led to dramatic weight loss that changed the look of his face. One cosmetic surgeon who spoke with the publication felt that Simon was overdoing the Botox and fillers, but that is only speculation.

Lean And Mean At Royal Ascot Days Ago

This very recent shot of Simon Cowell shows him at Royal Ascot days ago. He attended the 2021 event with his partner Lauren Silverman, according to Us Magazine. While Simon's expression in this candid shot didn't have his typical "cat who got the cream" vibes, he was looking great in his formalwear. The pic above comes from the simon.cowell.fans Instagram account. Simon is putting together a new musical reality TV game show in the UK, Walk the Line, so it makes sense that he was spending time in England. Although Simon isn't grinning in the photo above, he did get new veneers in 2020, following his serious e-bike accident.

Simon has changed over the years, but who hasn't? While his physical transformation is more dramatic than most, he has been through a lot lately, including the electric bike accident that left him with a broken back. America's Got Talent fans love Simon Cowell, whether he's had plastic surgery or not, and they always want more of his wit and humor, not to mention his reactions to AGT contestants like Jane "Nightbirde" Marczewski.
