They’re all in this together!

The High School Musical star Ashley Tisdale is engaged to musician Christopher French, Celebuzz can confirm.

And her future in-laws are already celebrating!

“He called us late last night to tell us the news and we are all so excited and can’t wait,” said French’s sister Monica Hebert. “We love Ashley and are excited to have her join our family.”

According to Life & Style, the Annie Automatic frontman popped the question in New York City Thursday night.

“It happened on the 103rd floor at the top of the Empire State Building,” an insider tells the mag of the proposal. “It was totally romantic and Ashley’s over the moon, of course!”

The 28-year-old has been dating French since December 2012. This is the first engagement for the former Disney starlet, who has been previously linked to director Scott Speer and Boys Like Girls rocker Martin Johnson.

Since news of the engagement surfaced Friday, the actress has only tweeted a cryptic message about her night, writing:

Best night of my life. We’re on top of the world
