Megan Fox Full-On Straddled Machine Gun Kelly At His LA Concert, Thereby Turning Their PDA Up To 11

Megan Fox and Machine Gun Kelly are not just dating — they are DATING-DATING-DATING.

And there has been all sorts of PDA.

Megan, of course, made a very memorable cameo in MGK's "Bloody Valentine" video last year...

Anyway, these lovebirds brought their touchy-touch to a new level over the weekend during MGK's show at the Greek Theatre in LA.

During a rendition of "Candy," MGK walked out into the crowd to serenade his GF, who was, obvs, present and accounted for.

And not only was Megan all about it, she hopped aboard the MGK train and made out with him. Like, a full straddle-kiss.

And you know what?? Love is love is love.

*wanders off humming what the world needs now is love, sweet love*...
