Celebrity birthdays in June

39 of 59: Prince William, son of Prince Charles and the late Princess Diana, turns 30 on June 21, 2012. He will receive a birthday present of about 10 million pounds sterling, or $15.7 million, which is the amount his mother left him in an inheritance fund, after taxes were deducted and interest was added.

According to Hello! magazine, which has covered the British Royals extensively for years, Diana's will called for the bulk of her estate to be held in a trust for William and his brother Harry and then given to them when they turned 25. After she died, executors changed the inheritance age to 30, the outlet says.

Check out photos of Prince William and his mother through the years. Did you know that on the day he was born, scores of people in celebrated outside the London hospital where Diana gave birth?
