The "Margin Call" actress turned 50 yesterday, and to celebrate the new decade of her life, Canadian-based cougar-dating website CougarLife.com (who specialise matching cubs and yummy mummies), crowned the actress with her new title.
Demi rose to celeb cougar status when she started dating "Two and a Half Men" actor Ashton Kutcher, who was 15 years her junior. The pair were married for six years before splitting last year amid rumours he cheated on his wife with a 22-year-old.Despite the unhappy ending to their relationship (which included a stint in rehab for Demi's "emotional" issues earlier this year), Claudia Opdenkelder told RadarOnline that Demi had "single-handedly done more for the cougar community than anyone and made significant strides in helping the lifestyle become part of mainstream culture."
While Demi was most recently linked to Kiwi actor Martin Henderson, it's believed she's currently single.
Ashton however, has moved on with his former "That 70s Show" co-star Mila Kunis. The pair were recently spotted in Sydney, mixing a business trip with pleasure as Ashton was in town to promote his latest business venture, airbnb, an online community-style holiday rental service.
