Rosie O'Donnell's mortal enemy, Donald Trump, kindly reached out to her via Twitter this morning urging her to get well soon after her heart attack earlier this month

"Rosie, get better fast. I'm starting to miss you!" Donald wrote.

The talk show host was as stunned as the rest of us and quipped in return: "well thank u donald - i must admit ur post was a bit of a shock ... r u trying to kill me ? xx"

The two began fighting in 2006 after Donald decided to pardon then Miss USA, Tara Conner, after she failed a drug test. For the past six years, the duo have been at odds, publicly throwing barbs and insults.

Rosie has called him an "snake-oil salesman" and Donald has dubbed her a "pig" and a "complete failure" after her talk show on the OWN network was canceled.

That being said, it's good to see these two showman know when to stop the act and play nice.
