Tyler Posey's mom Cyndi Posey has passed away, after a prolonged battle with breast cancer. Earlier this month, the Teen Wolf actor said that he was taking a little break from social media.

Although he recently returned to Twitter, and thanked everyone for their support, he was extremely vague about the reasons for his disappearance and fans speculated it was because of his mother's health struggles.

According to her obituary, she passed away on December 12th.

In the past, he's been very open about his mother's cancer, and even called her his biggest hero, so we can't imagine what he must be going through.
