Lisa Rinna may be in her 40s, but she's planning to pose nude for Playboy again, OK! reports. "I'm the worst liar on the planet, I can't lie," the former Dancing With the Stars contestant said when asked if she was planning on stripping down for the mag. "I think that could be a yes." The 45-year-old last appeared in Playboy while 6 months pregnant, 10 years ago.
