(CNN) – Don't expect Newt Gingrich to join the Mitt Romney administration, should he capture the White House in the next election.
The long-shot Republican presidential candidate on Thursday said he would enthusiastically support Romney, if he nabs the nomination, but that he would "probably not" serve in his cabinet.

"If the choice does end up being Romney versus Obama I could be very, very enthusiastic for Romney," Gingrich told WILM radio in Wilmington, Delaware. "I think that's a huge choice, but I've had a very good life doing a lot of fun things."
The former House speaker has vowed to remain in the Republican primary through the convention in August, despite trailing significantly in the delegate count and in polling across the board.
If or when he loses the GOP presidential nomination, Gingrich said he will spend time with his wife, Callista, his grandchildren, play golf and happily advise the next Republican administration.
"Callista's got me into being a really bad golfer. I'd like to move up from bad to mediocre," Gingrich said.
"I'm very happy to be an adviser. I did a lot of that in the Bush administration, both on health care and on national security," he added.
