Donald Trump Is against Rob getting back with Kristen Stewart

Donald Trump Tweeted to Rob saying "Don't get back with Kristen, she is a cheating Dog".

Just when you thought Donald Trump was going to weigh in on last night's presidential debate ... you were wrong.

Actually, Trump is much more interested in giving you his opinion on Robert Pattinson (Edward Cullen) and Kristen Stewart's (Bella Cullen) recent reconciliation. (Who knew he was a Twihard?)

The "Twilight" lovebirds were seen out and about together this past week, first grabbing dinner at the Chateau Marmont in Los Angeles, Calif., on Oct. 13, then heading out for drinks at Ye Rustic Inn in Los Feliz on Oct. 14 and then enjoying lunch with friends at Casita del Campo in Silverlake.

But The Donald is NOT a fan. The 66-year-old shared his two cents on Twitter, writing, "Robert Pattinson should not take back Kristen Stewart."

Why? Well, because she's a cheater.

"She cheated on him like a dog & will do it again -- just watch," Trump added of Stewart's affair with her "Snow White and the Huntsman" director, 41-year-old Rupert Sanders. "He can do much better!"

Apparently, Trump is good at dissecting relationships, or at least his followers think so. "@realDonaldTrump Any thoughts on Rihanna and Chris Brown?" one follower tweeted.
