Sara Leal’s best friend, Jonathan Rockelmann, reveals to RumorFix exclusively that the 22-year-old was worried that she might be pregnant with Ashton Kutcher’s child after a one-night stand.

Jonathan tells RumorFix exclusively that the San Diego resident took two pregnancy tests on Wednesday and both came back negative.

Leal told Us magazine that she and Ashton had unprotected sex two times and that she is not on birth control. Ashton’s camp has been silent since this scandal broke.

Jonathan says, “Sara is not on any form of birth control. She’s not as innocent as she came off to be in Us Weekly. She said it was her first one night stand, which is definitely not true.”  He goes on to say, “I used to live with her in college and she used to have one night stands then, but they were never celebrities like Ashton Kutcher or anything like that. It doesn’t happen all the time, but she does do it.”

And if Sara were pregnant, Jonathan says, “There is no way she would want a kid — even it it was Ashton’s — I mean, she would be set for life, but there’s no way she would deal with a kid or any of that sh*t.”
