From webbed toes and extra nipples to a tiny tail, some of the world's biggest stars were born with incredibly rare physical traits that make them stand out from the crowd.
While some have spent years keeping their anomalies hidden, others have proudly embraced their rare features and cite them as a source of pride.
Join HELLO! as we discover the A-listers that were born with some of the most unusual physical traits on record.
Ashton was born with webbed toes, and proudly showcased the anomaly on Friday Night with Jonathan Ross in 2008. "I have two toes that are connected, webbed," he explained.
"They are just a little connected…I heard this one little kid who had webbed toes, and he thought he was abnormal, but then he saw that I have them too, and it confirmed that he is abnormal."
"I thought everyone's toes were like that," the That '70s Show star added. "You can actually cut it when you are born. People's toes are joined, then grow apart. Mine just didn't [grow] all the way."
Harry is the owner of supernumerary nipples, meaning that he has a total of four nipples on his chest, with the extra two sitting lower on his abdomen.
The singer has joked about the abnormality in the past, and shared on BBC Radio 1 that it might be his "best trait".
"My worst trait is, I think I snore," he said. "Also, I quite like routine, so I don't know if I'm incredibly spontaneous because I quite like routine. Best trait, I don't really know. It's weird to pick a best trait. Shall we go with the nipples thing?"
Just like Harry, Lily was born with a supernumerary nipple. The 'Smile' singer's extra nipple sits under her left breast and "actually lactates", as she shared on Shopping with Keith Lemon.
The legendary M*A*S*H actor was born with the incredibly rare physical trait of brachydactyly, due to a congenital disorder called Poland syndrome.
As such, the fingers on his left hand are significantly smaller than his right.
Gary went to great lengths to hide the abnormality throughout his career, and would often keep his hand in his pocket or his lap while filming M*A*S*H.
"Of course, this defect affected me while I was growing up," Gary said in an interview. "I suppose when I was very young, I knew my disability would set me apart and make me special."
The comedian suffered from a birth defect known as clubfoot during his childhood, which occurs when a baby's foot or feet twist inward and downward.
