Katy Perry dating Riff Raff?! Rapper 'smitten' after 'romantic' date with John Mayer's ex, still flirts with sexy bootilicious side-chick amid collaboration rumors [VIDEO]

Rapper Riff Raff is one crazy dude.

Apparently, the Neon Icon emcee recently went on a date with "Dark Horse" songstress Katy Perry - and now he's smitten! Both singers posted a photo from their "romantic" evening on Instagram:

jodyhighroller: "ON A DATE WiTH KATY PERRY SHE iS PURDY." 

katyperry: "TBT to when I went on a date with Riff Raff aka @jodyhighroller also, regram!"  

Riff Raff would love to take Perry out again - but first he might want to stop admiring this other chick's booty:

Wonder if Perry will give him a chance after her failed relationship with John Mayer? Apparently Riff Raff might be ready to make things "official!"

Here's some exiciting news - apparently a new collaboration's already on the way? So if things don't work out romantically, at leas they still have their music to bond over!

Meanwhile, the "Ace of Space" rapper continues "enjoying the beautiful view" in Miami until "Katty Perry round two" comes along.

Funny guy. Did fans count how many times he smacked that bikini babe's bottom while talking about his "admiration" of Perry?
