The actress said she hunted down the movie memorabilia as a gift for her husband Tony Parker.
She told Sky magazine: "Tony's a huge Alien vs Predator fan. For the longest time he wanted these statues of the characters.
"I looked for them everywhere and finally found them, so that's what I gave him for Christmas.
"When they arrived I was like, 'Oh my God, they're so scary'. The alien even has the drool - they are absolutely terrifying!"
Longoria admitted last month that she was trying to persuade David and Victoria Beckham to play Cluedo against her and Parker.
