Donald Trump put his disdain for rival Rosie O'Donnell aside on Tuesday after learning she suffered a heart attack, and even sent the comedian a get-well message!

"@Rosie, get better fast. I'm starting to miss you!" Donald tweeted on Tuesday morning.

A far cry from the war he's waged on Rosie, calling her a "loser," a "pig" and a "bully."

After Rosie's show on OWN failed, Donald gloated saying, "I predicted correctly that Rosie would never make it. I did say that and she never made it so that was sort of good and I was very proud of that frankly."

But as Breaking Celebrity News reported on Monday, the former talk show host suffered a heart attack and blogged about the scare on her website, pulling at Donald's heartstrings.

"well thank u donald - i must admit ur post was a bit of a shock," Rosie tweeted back in response to The Donald's shockingly nice message.

"r u trying to kill me? xx"

After having an ache in her chest and arms last week, Rosie took Bayer Aspirin, but did not call 9-1-1 and waited until the next day to go to the cardiologist, where she was told that she had a heart attack and was sent to the hospital where a stent was put in.
