“This is very on brand for me,” the 37-year-old captioned the post. “I made a deal with this baby to let me make it to this before labor. Not sure what it wants in return but I’m CLEARLY a woman of my word. Such a fresh and inspiring take on the play!”  

Jazz continued to gush over the play, teasing that she “cannot put into words how special” the script is due to having “part pregnancy brain fog.” After all, this event doubled as an opportunity to debut her baby bump.

As for Brenda, this isn’t the first time she’s celebrated a sweet milestone in the Culkin family. In fact, the Running Point star honored her 8-year anniversary with fiancé Macaulay Culkin—who shares sons Dakota, 4, and Carson, 2—in a heartfelt tribute earlier this summer.  

“8 years and there is still no one who makes me laugh or smile like the way you do,” Brenda wrote on her June 18 Instagram post. “No one who makes me feel more seen, heard or loved. My partner in crime, my adventure partner, my best friend, my baby daddy, my favorite everything- thank you.” 

Still reflecting on their sweet romance, she added, “To be loved by you is the greatest privilege. Happy anniversary. I love you.”
