Ashley Tisdale and Vanessa Hudgens became friends during High School Musical

Her pregnancy announcement comes after Vanessa Hudgens revealed she was expecting her first child at Vanity Fair's Oscar party.

The duo were once best friends during the height of High School Musical's success, but what happened to their friendship?

The pair reportedly haven't interacted since their mutual friend Sarah Hyland's wedding in 2022, but have not been seen together since.

Tisdale and Hudgens were incredibly close to one another after meeting on the set of High School Musical.

Hudgens was part of Ashley's wedding party when she tied the knot in 2014, but Ashley Tisdale was nowhere to be seen when Hudgens married MLB player Cole Tucker in 2023.

Ashley's absence at her former best friend's wedding was spotted by fans who have been speculating about their friendship ever since.

But what caused the breakdown of their friendship?

The main theory is Vanessa Hudgens and Austin Butler's split was the catalyst for their fallout.

Ashley Tisdale was incredibly close to Butler, who is actually her long-lost cousin, but who also starred in multiple projects with her.

Many believe the actress took his side following their break-up but they have never publically responded to the rumours.

Others believe the friends simply just drifted apart as their lives took different paths. They were busy with their careers and personal lives, and sometimes you just drift apart, even when you're famous.

Both actresses being pregnant at the same time is making High School Musical fans feel nostalgic, but maybe the joint milestones will bring the friends back together.
