Congrats go out to Ashley Tisdale!

The 29-year-old actress married musician Christopher French on Monday, Sept. 8, according to People. Tisdale took to Instagram to confirm the news, posting a wedding photo and writing, "Best day of my life! Introducing Mr and Mrs French Sept 8, 2014 Shot by @corbingurkin."

In the photo, Tisdale wears a gorgeous white gown with cap sleeves and a flower crown.

According to E! News, Tisdale's "High School Musical" co-star and best friend Vanessa Hudgens was among those in attendance.

Tisdale and French, the lead singer of Annie Automatic, began dating in December 2012 and got engaged in August 2013.

"You know, I didn't [think it'd happen that quickly]," she told Ryan Seacrest last year of her whirlwind engagement. "I think I've obviously been in long relationships in the past, but I think because of knowing what I wanted, I wouldn't have gone into a relationship, if it wasn't what I wanted. And I think from the moment that him and I met, I just knew it."

Cheers to the happy couple!
