The 30 minutes of X-rated footage was shot in New Mexico and features the `Friday Night Lights` star with an ex-boyfriend.
It is not clear when the tape was made but TMZ.com reports it is possible the 32-year-old beauty was under the age of consent when the footage was filmed.
However, two songs from Brandy`s `Never Say Never` album, which was released 16 days before Minka turned 18 in June 1998, feature in the background but it is possible the music was added afterwards.
The tape is shot in a semi-professional manner, with the camera secured by a tripod and hooked up to a TV monitor so the couple could watch and Minka is said to be "very aware" of the camera.
A spokesperson for the actress has not yet commented on the alleged footage.
Minka was recently romantically linked to TV star Wilmer Valderrama and counts baseball player Derek Jeter and musician John Mayer among her ex-boyfriends but has previously described her dog Chewbacca as the love of her life.
She said: "I can`t get enough of this wookie! He is the love of my life."
