Someone look up to make sure pigs aren't flying around up there. After years of fighting, making up, then fighting some more, Rosie O'Donnell has reached out to Elisabeth Hasselbeck ... via Twitter.

"Hey -- how r ur new babies? -- how is gracie? I saw her photo -- she is beautiful ..." tweeted the distinctively brief Rosie on Sunday.

Elisabeth responded tweeting, "kids are great @rosie I bet yours are keeping you smiling! Are we really talking on twitter? How about lunch? Gluten free pizza & good talk."
