Jason Derulo Fires Back At Ex-Girlfriend Jordin Sparks: Singer Shows Off New "Castle" – Response To #ByeFelicia, "Look At Me Now" [PHOTOS]

Jason Derulo is talking dirty to his ex, Jordin Sparks, and dissing the singer by being mute to her new song diss released on her mixtape, #ByeFelicia.

MStars News has learned that the singer just bought himself a new house, well a castle. Sparks seems to be the least of worries on Derulo's mind, because he was too busy uploading his new pad, and promoting his album, that will be on sale Black Friday.

"Derulers! #TalkDirty is going on sale 4 #BlackFriday this week for $5.99 on @iTunes! If u already purchased songs from the album u can choose the "complete my album" feature & get it 4 as low as $2! SALE ends 11/30! Make sure ya go get it! smarturl.it/TalkDirtyAlbum," Derulo captioned the photo above.

The singer's house is huge from the looks of the snapshot below.

One question we have for Derulo...does he plan on living in that huge mansion all alone?

According to TMZ, Derulo's new home is worth $3 million and located in the San Fernando Valley. The castle fit for a royal family is 10,000 square feet, layered with turrets, the house has a dungeon, and a basketball/tennis court, as well as a swimming pool.

It looks like Derulo is living it up and not worried about Jordin's words where she basically called him an ungrateful b#tch.

In "How 'Bout Now (Remix)," Sparks sings:

Member I deleted all my other guys numbers on my phone for you.
Member when you broke your neck and I had to wash your back for you.
You probably don't remember half the shit that i did for you.

Once you blew up, head got big and you started changing.
Can't believe all the things that you started saying.
Like I'm with you for your fame and your name. What?

Derulo is probably gearing up for a housewarming as Jordin releases her new mixtape.
