WASHINGTON — In an announcement that is sure to send ripples of speculation throughout the political punditocracy and cable news world, longtime “Morning Joe” co-hosts Joe Scarborough and Mika Brzezinski are engaged.

According to the “Today” show Thursday morning, Scarborough, 54, a former Republican congressman-turned political talk show maestro, has proposed to Brzezinski, 50, his co-host and daughter of former Carter National Security Adviser Zbigniew Brzezinski.

They have led the MSNBC morning gab fest together since its inception in 2007.

Both have children from previous marriages.

An MSNBC spokesperson told The Associated Press that the couple is engaged, but said the network wouldn’t be commenting further.

“We have a crackling on-air chemistry, and a crackling off-air chemistry, too,” Scarborough told The Hollywood Reporter last month.

The date of the wedding has not been announced.
