Ashley Tisdale Shenae Grimes toast boots wedding ring army jacket jeans stripes

Who knew they were friends?!

Ashley Tisdale and Shenae Grimes grabbed a bite at Toast in West Hollywood yesterday, and we bet the 90210 actress was offering some wedding tips to the High School Musical star!

The brunette beauty married husband Josh Beech in May 2013, and The Tiz is engaged to her rocker beau Christopher French, so we have a feeling they might have been comparing notes on details like place settings and flower arrangements.

Either that, or they were just hungry!
