Prince William looks strikingly similar to his late mother, Princess Diana, according to several social media users.

The late Princess of Wales would have turned 63 on Monday. It has been nearly three decades since she passed away, but Princess Diana is still warmly remembered by royal fans, especially because her eldest son, Prince William, inherited her genes and looked like her.

One video on TikTok featured a 16-year-old Prince William when he became a godparent for the first time in 1999. In the clip, he can be seen carrying Prince Constantine Alexios of Greece and Denmark. However, his facial reaction caught the social media users' attention as it was very similar to Princess Diana's.

"Prince William looks so much like his mother Princess Diana," the caption read.
