Ashley's beau Christopher French popped the question last week, and she's been looking every inch the stylish bride-to-be ever since.
The Phineas and Ferb star indulged in a spot of retail therapy at Fred Segal in West Hollywood yesterday (14 August), whilst flashing her huge sparkler.
She opted for a laid-back look with an embellished oversized mint knit and flat sandals.
But the star of her outfit was her gorgeous white Céline Phantom bag - she even has one in yellow too. Lucky girl!
Come nightfall, the blonde starlet upped the ante in a mirror print bodycon dress as she attended the 12th Annual InStyle Summer Soiree.
She added baby pink courts and toted yet more designer arm candy, this time in the form of a Prada envelope clutch.
Jealous, us? Absolutely!
