PETA, a puppy and Pam -- Happy Valentine's Day! Baywatch alum Pam Anderson stars in a steamy new PSA for the nonprofit released Friday, Feb. 14 in which she strips down to nothing at all.

Sporting her blonde pixie cut, Anderson, 46, playfully disrobes in the black-and-white burlesque-style video while wearing lingerie and eventually nothing. The mother of two kids bares her toned lean physique as she sexily removes each clothing item in the clip, which ends with a totally nude Anderson cuddling in bed with… her puppy!

PETA specifically released the video dubbed "La Chienne" (French for "The Dog") to ask pet owners to keep their dogs indoors as large swathes of the country have been hit with snow storms and arctic temperatures.

Along with her cute pooch, Anderson is celebrating Valentine's Day with a special someone -- husband Rick Salomon -- whom she secretly remarried recently. The news of her second-time marriage to the film producer was revealed after the Playboy cover girl flashed a diamond ring at on that finger and fielded questions regarding her new bling.
