The Flight Attendant star, 37, is soaking up the sun at a tropical destination in her latest Instagram snaps with boyfriend Tom Pelphrey, while the couple gets in some relaxation time ahead of their baby girl’s arrival.  In October 2022, Cuoco announced via Instagram that she and Pelphrey, 40, are expecting their first child together. The little bundle of joy is supposed to arrive sometime in 2023, although the parents-to-be haven’t revealed an exact due date.  For now, they seem to be enjoying life as expectant parents, as they appeared to be living it up in the set of polaroid pictures Cuoco shared to social media on Wednesday, Jan. 4. In the Instagram carousel post, Cuoco is seen in the first image baring her baby bump in nothing but an oversized button-down dress. Another shot shows Pelphrey posing in his swim trunks while standing in front of a scenic background filled with palm trees. The pair also posed together for a mirror selfie, as they both raised an arm to flex their muscles for the camera. The final photos features the Big Bang Theory alum laying down on a lounge chair in a black bathing suit while cradling her growing baby bump.  Cuoco left the caption simple, adding just a series of various emojis, “🏝️ ♥️ 🤰🏼 💓,” next to the post.  Many of the actress’ friends couldn’t help but gush over the sweet photos, including Lacey Chabert, who commented, “Awww so beautiful!” under Wednesday’s post.  “Mama…. Here we go!!! So excited, boo!!!!” actress Ashley Jones wrote to Cuoco, while She Hulk’s Griffin Matthew aptly quipped, “MOMMY & ZADDY.”
