Now this is the perfect summer dress, good job Ashley!!

The star was seen in Hollywood at the premiere of The Lucky One. The movie stars Zac Efron who Ashley has been friends since they were in High School Musical together.

Ash tweeted: "Can’t wait to see ma boy Zac in his movie The Lucky One tonight!"

What a good friend!... but more importantly, what do you think of the dress?
