Ashley Jensen and Jenna Elfman: Preggo Pals

Michael Tran/FilmMagic

Having a pregnant buddy in the office is always a plus, even when the office is a sound stage. Moms-to-be Jenna Elfman, 37, and Ashley Jensen, 40 — costars on the upcoming CBS sitcom Accidentally on Purpose — have found a kindred spirit in each other over the past few weeks and months, Ashley tells OK!

“I was asking Jenna for advice on a daily basis anyway because she’s already had a child, so now, we’re going through it together,” she explains.

“One day on set she had a little wave of nausea, and she was like, ‘I don’t feel very well,’ so I had to go up and get some little saltine crackers and pretend they were for me — because nobody else knew at the time.”

The show tells the story of an unplanned pregnancy, and while Jenna’s baby-on-the-way appears to have definitely been planned, the show will mirror real life in other respects. “The first season will end in the birth, and that’s how it will be for me, too,” she notes.

The question of whether her real life bump will outpace that of her character remains to be seen, however! “I’m showing so much more this time, much sooner,” she concedes to Us Weekly. “I look way farther along than I am, so that feels different.”

“I’m like, ‘Am I going to plateau, or is it going to become humongous?’ I don’t know, we will see. It will be an adventure!”

An adventure Bodhi Elfman will happily accompany her on. Of her husband of 14 years, Jenna raves “he’s a total dream,” adding,

“Before bed sometimes, or in the middle of the night, I’ll be like, ‘I need orange juice!’ so he’ll go get it.”

Jenna and Bodhi’s baby-on-the-way — whose sex the couple will learn prior to delivery — is due in March, and will join the couple’s 2-year-old son Story Elias at home. Ashley’s baby-on-the-way — a delivery surprise — is due this fall and will be the first for her and husband Terence Beesley.

Accidentally on Purpose premieres tonight at 8:30 p.m. on CBS.
