Lily Aldridge in Gucci | 2012 GRAMMY Awards

Lily Aldridge joined her husband Caleb Followill of the band Kings of Leon along with his brothers — and band-mates — Jared Followill and Nathan Followill last night for the 54th Annual GRAMMY Awards.

The 26-year-old Victoria’s Secret model — and expectant mother — proudly showed off her growing belly in a gorgeous silk chiffon long sleeve floral gown with plunging neckline, voluminous skirt and high side slit from the Pre-Fall 2012 collection by Gucci.

I hope this is just a glimpse of what we can expect her pregnancy style to consist of! I already loved the touch of floral print on the dress featured in the presentation, but the shades of indigo, black and grey in the all over print on Lily were just beautiful.

Lily styled her hair in a chic center-parted bun and wore jewelry — including thin silver hoop earrings — by Anita Ko.

Black peep toe pumps and a black suede clutch with enamel and gold tiger head chain detail completed her look.

FYI: The men of KOL looked super dapper last night! Check them out in Gucci!
