Megan Fox Lip Injections?

It seems like there is a never ending whirlwind of speculation regarding Megan Fox and whether or not she has had any plastic surgery.

So i ask you, the fans of Megan Fox, to weigh in on the topic of lip injections.

Her lips really do seem more plump in some of these photos, but is it the result of lip injections, of just different lip gloss?
