But, don't (repeat, DON'T) expect to see her in gonzo any time soon. Fact is, according to her interview with AVN after parting company with Vivid, Lexie makes it very clear that she didn't re-sign with Vivid because they wanted her to do more extreme and hardcore scenes--and she wasn't ready for this type of action (Anal and b/g/b IR were mentioned in the AVN article as what Vivid was asking for).
Also, Lexie Marie is no longer listed on the LA Direct talent agency website as being rep'd by them--so she may be on a "time-out" from video porn. The sexvid you mention was probably made right after splitting from Vivid, in order to prove she was still "book-able".
Lexie Marie's "MySpace" page shows her hangin' with her rocker boyfriend. (Yep...get in a no-contract band, and you, too, can bag a beautiful porn babe.)
