(CNN) -

Donald Trump and Rosie O'Donnell are well-known for their public spats, but for once the two shared a tweeted exchange that didn't contain any fighting words.

In light of her heart attack, which O'Donnell wrote about on her blog Monday, Trump wished his media adversary to get well soon.

"@Rosie, get better fast. I'm starting to miss you!" Trump posted Tuesday.

O'Donnell graciously but skeptically accepted his well wishes. "[W]ell thank u donald -- i must admit ur post was a bit of a shock," she wrote in response. "[R] u trying to kill me ?"

We'd guess it's more like he needs his verbal sparring partner healthy and ready for battle. O'Donnell, 50, said Monday in her post addressing her heart attack that she's "lucky to be here" and "happy to be alive."
