Ashley Tisdale welcomes 1st child with husband Christopher French

Congratulations are in order for "High School Musical" alum Ashley Tisdale, who gave birth to her first child, a daughter, on Tuesday.

Tisdale, 35, shared the happy news on Instagram by sharing a sweet black-and-white photo of her holding her newborn's tiny hand. The Disney star also revealed her little girl's adorable name.

"Jupiter Iris French arrived earth side 3.23.21," wrote Tisdale.

Well wishes quickly came in from names including Vanessa Hudgens, Emma Roberts, Lea Michele and Corbin Bleu. "Congratulations to you, Chris and the family," Bleu enthusiastically commented while Roberts called Jupiter an "Angel!"

Tisdale also received some positive vibes from fellow Disney Channel-alum Hilary Duff, who is about to give birth to her third child any day now. "Jupiter [sparkle emoji,]" gushed Duff in the comment section. "Welcome little girl."

Her husband, Christopher French, whom she wed in 2014, shared the same good news on his social media.

Prior to welcoming her little one, Tisdale opened up about her changing relationship with her body on her personal blog.

On March 19, she penned an open letter to her pregnant body and detailed her struggle to accept it.

"I popped pretty early in pregnancy, and I had people say 'I think you’re farther along than you think', 'Are you having twins?'—all very invasive things," she recalled. "I brushed those comments off as I do with any type of criticism."

Tisdale also looked ahead to her post-pregnancy days, adding, "I don’t know what my body will be like after the baby comes, but I do know I’m going to give it time, let it heal, and take really good care of it."
