A hearty happy birthday is due for Ian Somerhalder today, but The Vampire Diaries star doesn't want a card, a hug or even an iPhone 4 from fans.

Instead, the 33-year old would love fans to donate to his IS Foundation, a charity that looks out for the environment and which has already changed Canadian sled dog laws; delayed the Keystone XL Pipeline; and banned shark fins in California.

Miley Cyrus turns 19 years old today, marking the occasion in the same way she's spent the past few months: By remaining relatively quiet.

The singer/actress has not been in the news much lately, with the exception of a recent Tweet that called out her body image critics. But Miley's boyfriend, Liam Hemsworth, is making far more headlines than his gal pal these days, thanks to his upcoming role in The Hunger Games (watch the awesome trailer NOW).
