Does Demi have a new guy?

Twist can confirm Demi's been spending tons of time with Rob Kardashian in the pic above, the couple hugged after going bowling! And the very same day, Rob tweeted these lyrics from Kanye West's song "Bittersweet": You're gonna be the death of me/I don't want you, but I need you." So, are they going to make it official? Lately, Demi's hesitant to get a BF.
