Ke$ha leads cancer chat campaign

Pop star Ke$Ha is urging parents to be candid with their kids about cancer as part of a new health campaign.

The TiK ToK singer stars in a new commercial for FCancer, an organization which aims to put an end to the late diagnosis of the killer disease.

In a specially-filmed video, Ke$ha encourages families to sit down together and discuss the condition, so kids will understand the signs and be able to detect it early.

Actress Sophia Bush and Adrian Grenier have also filmed clips for the campaign.
