Spencer Pratt, Miley Cyrus Tweet, Plan Double Date

For reasons unknown, Spencer Pratt decided to post his cell phone number on Twitter Wednesday night - and none other than Miley Cyrus rang him up.

"is it weird that @spencerpratt put up his "number" on twitter and i called? haha :)" the popular teenage Disney corporate drone later Tweeted.

Spencer Pratt cleverly replied on Twitter: "is it weird that I am secretly your biggest fan!!! I'm crushed I missed your call! I will be answering all day!"

The Hills villain later wrote: "i gave you my other cell phone number in direct message that way when you call Speidi will pick u up! i owe both you and justin... i owe you both the biggest milkshakes they can serve!"

Wow. We love third-person nickname reference of Speidi. Maybe he can freestyle about this scintillating Twitter exchange in his next rap song.

Spencer also invited Miley and her Billy Ray Cyrus-look-alike boyfriend, Justin Gaston, on a double date with he and his plastic wife, Heidi Montag, after Miley complained about getting spammed from Spencer's "number."

"@mileycyrus let's double date you and @justinmgaston and Heidi and I! We can get millshakes!" Pratt said.

Miley Cyrus' response?

"im down! you owe me a milkshake anyhoo since i got suckered into calling your voicemail thing and now 'you' keep texting me ha," she said, adding:

"i'll just send my cell phone bill to you ;) love yall!"

You may officially be dumber for reading this, but you can at least happy that these two awesome couples will soon be sharing milkshakes together.
