Sounds extremely fake... T&A isnt a selling point for Alien films, infact I think the ONLY Alien film I can think of that had the T&A aspect (if you can call it that) is AvP: Requiem. A few bubbly teenage girls with nice bodies that get merc'd. Boy meets girl aspect and thats about it...
Unless you wanna count Ripley banging Clemens in A3... and thats REALLY pushing it!
Oh and MAYBE whats her face in A: Resurrection in her knickers getting a massage from the guy who played Top Dollar in The Crow.
