"Best night of my life," tweeted Tisdale. "We're on top of the world."

Now the "High School Musical" star is showing off the massive rock the Annie Automatic musician gave her (above photo) and thanking her fans on Twitter, writing, "Thank you guys for all your well wishes. Means so much to me. We're so grateful and excited. #imthehappiestgirlintheworld ... I'm feeling truly blessed right now, it's overwhelming :)."

There is no word yet as to when the wedding will be. Tisdale and French, who a source describes to US Weekly as a "darker, bad boy" type, have been dating since December 2012.
