The newest bundle of joy will join Claire and husband Andrew Joblon's two children: son James Holt Joblon, 4, and daughter Elle Holt Joblon, 2.

Andrew, who tied the knot with Claire in 2018, recently celebrated his wife on Mother's Day 2023, sharing a throwback post of their family dressed up in Starbucks uniforms. "Happy Mother's Day to the [GOAT]," Andrew wrote. "We love you so much."

Claire cheekily continued the Mother's Day festivities by posting a video of herself asking James and Elle, "Who's your favorite, mom or dad?"

It was a unanimous decision, as both kids answered, "Mom."
