Donald Trump created quite the Twitter stir when he sent a Tweet Wednesday warning Robert Pattinson to stay away from Kristen Stewart.

“Robert Pattinson should not take back Kristen Stewart,” Trump, 66, wrote, explaining, “She cheated on him like a dog & will do it again — just watch.”

Sounds like he knows from experience.

“He can do much better!” Trump added.

Apparently the cautionary advice comes on the heels of news that Pattinson and Stewart have reconciled after Stewart admitted to cheating on her beau.

When Trump got some feedback from his followers, he took to Twitter once again. “Lots of response to my Pattinson/Kristen Stewart reunion,” he wrote. “She will cheat again–100 certain–am I ever wrong?”

Do you really want us to answer that Donald? Does the name Marla Maples ring a bell?
