Denise Richards is in mourning after becoming the latest star to lose a parent during what is being called 'Black November' for celebrity moms and dads. The actress' mother, Joni, has lost her battle with cancer.

Richards took time out from her acting career last year to care for her ailing mom and revealed the cancer diagnosis gave her a new perspective on life.

She revealed, "I've just gotten to the point where life is so short and I just want to be happy."

November was a terrible month for celebrity-related deaths - Jonathan Rhys-Meyers, Kanye West, the Osmonds, Jane Seymour and British actress Kelly Brook were among the stars who lost moms and dads during the month.
