The Disney alum, 35, and her hubby, 39 — who tied the knot in 2014 — announced they were expecting in September before revealing they are having a baby girl one month later. "This year has obviously been hard," she captioned a photo of herself with French from their gender reveal party. "For so many. Ups and downs, and an emotional roller coaster.
"I think this day was by far my favorite day EVER! I cried I was so happy," the excited soon-to-be mama added. "P.S. for all you people going above and beyond for gender reveal parties. A cake with the color inside is JUST as rewarding as fireworks but SAFER! #SheSoFrench."
The High School Musical star has since shared behind-the-scenes photos of her growing baby bump with her 13.2 million followers.

Tisdale bundled up in a tan Madhappy sweatshirt, high socks and fuzzy slippers for her coffee pick-up.
Looking almost unrecognizable, she donned dark shades and two masks.
Despite her baggy sweatshirt, Tisdale's (very large) baby bump was on full display while she waited for her order.
The blonde babe headed back to her car, where French was waiting for her.
Her loving husband couldn't help but gush over Tisdale and her baby bump, calling her a "superhero" in the comments section.
