Shannon Tweed will celebrate her 50th birthday this week. Both her and her partner, Gene Simmons of KISS, are going to go ahead with facelift surgery on their TV reality show "Gene Simmons Family Jewels."

Tweed says it was Gene's idea but she wasn't about to let him look younger than her so she is going ahead with it too. Tweed achieved fame when she became Playboy Playmate of the year in 1982. They never married but she has been living with Gene Simons since 1983 and they have two teenage children.
