Kaley Cuoco’s trip around the sun was a big bang.
Indeed, the Big Bang Theory alum shared a look into her 40th birthday celebration with her loved ones, including fiancé Tom Pelphrey.
“This is 40. What a year, what a decade, what a life!” Kaley wrote on her Dec. 2 Instagram post, which sees her drinking martinis with her friends. “I had an amazing west coast surprise party that took my breath away, and last night, the sweetest most fun east coast bday dinner (at my favorite NY restaurant) with some of my nearest and dearest.”
For the special occasion, the Flight Attendant actor—who shares daughter Matilda, 2, with Tom—wore a black silk jumpsuit, her brown hair slicked back into a low ponytail. Her fiancé also matched her vibe, sporting an all-black look.
She continued in the post, “I feel so grateful for every moment I have, and the crazy road that led me to this moment in time. I adore my family, friends (and animals) and thanks to each of you for making this very special birthday feel extra extra special.”
Kaley also showed her love and gratitude to Tom, who helped plan her birthday weekend.
“You always go the extra mile to make me feel like the most loved girl on this planet,” she dedicated to the Love & Death actor. “How lucky I am to live this life with you.”
But that wasn’t the end of her celebration. After dinner, the couple—who got engaged last August—also saw a show in the city’s Paris Theater, a spot Kaley revealed they first “met 3 ½ years ago.”
As for her west coast bash? She traded in her upscale couture for a trucker hat and matching bolo tie at her western-themed party. And true to their chemistry, Tom offered a glimpse into the event in his own Instagram post, which doubled as a birthday tribute to his “favorite person.”
“I didn’t get to see your first few chapters, but I am so damn happy I get to be here for this one, and every one to come,” he captioned the Dec. 1 post, including several photos of Kaley over the years. “You have a massive heart—one that holds all the dogs and all the animals who need protecting, all the work, all the friends and all the family—and still, somehow you make me and Matilda feel like we are the only two people on the planet.”
Tom ended the tribute, “Happy happy birthday to the sexiest, coolest, funniest— may you feel all the love you constantly give.”
