Aisling Bea, 40, shares she's pregnant with first baby as A-Listers help her announce news

Aisling Bea is expecting her first child, and announced the news with a little bit of Hollywood help.

The This Way Up star, 40, took to Instagram on Monday evening to announce her pregnancy in true comedy-style.

Aisling shared the exciting news by debuting her blossoming baby bump at the Big Slick event over the weekend.

In a carousel post, the mum-to-be can be seen with a cartoon face painted across her bare stomach in black ink, as she posed alongside American A-Listers Paul Rudd, and Taylor Swift's boyfriend Travis Kelce.

"Dignity Intact. Got pregnant so I could try & put something beside Paul Rudd’s face to make him look older," Aisling began her caption.

"Thanks to the @bigslickkc , Paul, @sethherzog super boy @travisKelce & mostly our angel @sherylcrow for helping me show off my bump in the most dignified & classy way possible," she playfully went on to say.

"Sheryl said myself & Seth could be her very professional back up dancers with our ridiculous idea, how on brand!She really does just wanna have some fun, yawl."

The Avoidance actress continued her appraisals, adding: "And thanks to @jackoby.freeman & @elsie for doing full bump glam & to one of them in particular for getting me pregaroo in the first place.

"Just to note if you use sharpie pen on your skin, it will be there for about two days. Just if you are weighing up what a commitment to an idea is worth. Gentle dermatitis is the answer."

"**edit to save myself admin. Yes I am pregnant. This time it’s not a joke about bread," the caption ended.

Fans were quick to congratulate the actress on her exciting news and creative announcement.

One fan @anoushkalucasmusic gushed: "This is the best pregnancy announcement I’ve ever seen. Hope you and bump are very well!"
