Ashley Tisdale is ending her single days in style! The 28-year-old Disney star is engaged to musician Christopher French, and she just celebrated her bachelorette party in Miami — along with fellow High School Musical alum Vanessa Hudgens, and other friends.

"Off to a very exciting weekend :)" Ashley tweeted on May 15.

She later posted a photo with her "Bachelorette" sash, writing, "Weekend with my girls @nikkilee901 @msmorganashley @mikaylas_mom @gypsyraja @kimhidalgo @shelleybuckner @dawneefish #turnup4TIZ."

According to Us Weekly, Ashley and friends appeared to party at Purdy Lounge in Miami, and celebrated out on a boat. A couple of those friends shared the photo above, showing the girls in party mode.

Ashley and Christopher got engaged in August 2013 when he proposed from the top of the Empire State Building in NYC. "It was totally romantic and Ashley's over the moon, of course!" an insider told Life & Style at the time. Ash and her beau have been dating since December 2012.

In December 2013, Ashley gushed about her fiancé to On Air with Ryan Seacrest, explaining why they got engaged after only dating for about eight months. “I think because of knowing what I wanted, I wouldn’t have gone into a relationship if it wasn’t what I wanted,” Ashley said. “And I think from the moment him and I met, I just knew it. I was like, ‘Okay, this is the guy.’ And he knew the same thing. It was just this feeling that it doesn’t get any better. I can’t explain it!”

She did explain it pretty well, though, adding, “With other relationships, you’re trying too much and trying to make it work and then there’s just a moment when you find somebody and you’re like, ‘Holy sh—t! This is so natural! I had no idea and I did not think this would happen and I was just so focused on other things and then suddenly it just kind of hits you.”

She sounds so happy and in love. Congrats to the happy couple — and good luck with the wedding!
