The 36-year-old actress announced on social media earlier this week that she and her husband Cash Warren - who are already proud parents to daughters Honor, nine, and Haven, six - would welcome a son into the world when the star gives birth.

And now, the 'Sin City: A Dame To Kill For' star has admitted she couldn't be more excited about the news, as she says raising her first son will be a "whole situation".

She said: "We're super stoked. It's gonna be a whole situation."

Jessica also revealed she and film producer Cash, 38, are considering a name beginning with H to keep the theme they started with their two daughters, however the brunette beauty isn't too fond of her spouse's suggestions.

Speaking about her son's possible moniker, she said: "[Cash] said, 'We should name it Dick with a silent H.' He thinks it's like old school."

The 'Fantastic Four' actress - who married Cash in 2008 - has been craving Japanese food, and although she "dreams" about dessert, she's trying her best to stay away from sweet treats.

Speaking during an appearance on 'The Tonight Show Starring Jimmy Fallon', Jessica said: "I didn't think I was craving anything until I realised I'm craving Japanese food all the time. I actually dream about desserts but I'm trying not to gain so much weight with this baby. [I want] all the shaved ice with ice cream on the bottom."

Jessica's comments come after she took to social media to reveal the sex of her unborn baby on Wednesday (25.10.17).

Alongside a video of the big reveal, Jessica wrote: "@cash_warren and I couldn't be more thrilled to announce... #officiallyoutnumbered #babyboy #cantwaittospoilhim #hugsandkissesforlife #soontobemamaofthree (sic)"

In the short Boomerang video, Jessica can be seen standing with her daughters, who tug on a string that releases a whole host of blue confetti from an Honest Company box onto them.
