It looks like Katy Perry wants to throw a little rap into the mix on her Prismatic Tour.

Rapper/singer/songwriter (and model) Becky G will open up for the "Dark Horse" singer on four upcoming Prismatic stops -- two in Houston and two in Mexico -- starting October 10.

Becky made the announcement on Monday (March 24) in a quite elated Instagram video saying, "What you heard? It's real."

Becky and Katy will put on two shows in Houston, on October 10 and October 11, then head to Monterrey on October 14, and Mexico City three days later.

For KatyCats not familiar with the "Becky from the Block" singer, after getting her start on YouTube, 17-year-old Becky launched to stardom through collaborations with the likes of Cher Lloyd and Cody Simpson, whom she opened for in his first-ever headlining tour in last fall.

And if she brings any of her show-opening tricks from that tour to Prismatic, fans are in for quite the party.

"I think you can expect my set to be fun," Becky G told MTV News before she hit the road with Mahone on his MTV Artist to Watch tour last fall. "I definitely want to get the party going before Austin hits the stage, and I'm a dancer. A lot of people don't know that, so I'm definitely a groover. You'll see some cool moves onstage."

Both Perry and Becky G are COVERGIRLs, so we're sure they'll have great chemistry.
