Now, the Twitter-sphere has been sent into a spin again, this time because of another loving moment the two friends shared at the memorial service for Arizona senator John McCain on Saturday.
In a cute moment, former President George W Bush delivers a small piece of candy into the hand of former first lady Michelle Obama. A camera inside Washington DC's National Cathedral captured the moment, and it soon went viral.
Fittingly, the moment came in the front pew as former senator Joe Lieberman talked about the importance of bipartisanship, and reaching across the political isle.
How very apt!
