So recently, an article was published on Wonder Girls’ new US album and related information, and they hinted at the girls working with a world-renowned artist.

“Representatives of JYP Entertainment revealed to allkpop, “Their upcoming release, ‘Like Money’, is the work of songwriterCri$tyle, who has previously worked with artists like Rihanna, and JYP Entertainment producer Woo S. Rhee ‘RAINSTONE‘. There will be a special artist also collaborating with the girls on the song, and although the identity hasn’t been revealed yet, rest assured that they’re world famous in that they’ve already amassed over 40 million likes on Facebook.””

I’m speculating that the artist in question is none other than Katy Perry! How did I make these connections? Well, let’s see…
… Katy Perry’s facebook page has around 44,000,000 facebook likes…

They’re on friendly terms…

(Look at Lim! Notice how she changed from the first pic taken in 2010, to the second pic taken in 2012. She went from “OMG it’s Katy Perry!!!” to “Yeah, I’m friends with this chick” – They must have kept in touch or something!)

And she has previously mentioned that she’d like to work with the Wonder Girls…

“When asked which Asian artists she wanted to collaborate with, she immediately said the Wonder Girls, mentioning also that she would also like to steal their outfits!”

So is Katy Perry the mysterious artist? We’ll just have to wait and see when the song and MV are released!
And if you haven’t checked out the preview for “Like Money”, do have a look – it’s a hit!
