"He's an impressive sleeper (thank god!) & I'm his biggest fan," says the star's tweet.
Bodhi also took to Twitter Friday writing, "Shazaam! Easton Quinn Monroe Elfman. Born March 2 @ 7:53AM. Triple Word Score, Grand Slam, Royal Flush! Digging this guy big time."
Easton joins big brother Story Elias, 2 ½.
Jenna, 38, admits the pregnancy was planned around her show's shooting schedule.
“It was like an afterthought perk. I thought, 'Well, if the show gets picked up that could be cool. I can have my next kid and I won't have to hide it.’ You know, I'm not in my early twenties so I got to get busy."
The Elfmans, who recently celebrated their 15th wedding anniversary, announced the pregnancy in Sept.
