Ashley Tisdale and Vanessa Hudgens are "out of touch, out of sight, out of mind with each other".

The former BFFs - who co-starred in 'High School Musical' together - are both pregnant but they are unlikely to be sharing playdates with their little ones after drifting apart.

A source told DailyMail.com: "Vanessa and Ashley have two completely different lives. If they were in the same room, it would feel as if time didn't pass, but being in that room might be 30 years from now.

"Ashley only wishes the best for Vanessa, especially now that she is pregnant, and if Vanessa in any way reached out for advice on motherhood, Ashley would give it out almost immediately.

"But Ashley doesn't anticipate any future play dates on the horizon. They are out of touch, out of sight, out of mind with each other."

When Ashley welcomed her first child, daughter Jupiter, in 2021, Ashley couldn't wait to introduce her to Vanessa, who she called 'Aunt Nessa.'

But, the pair have since drifted apart and are no longer as close as they once were, although friends are keen to stress that they have not had a falling out.

The insider said: "There isn't a feud. It is basically that 'High School Musical' is just like High School. You keep in touch with some people forever, you see some people from time to time or never again.

"If Ashley doesn't see Vanessa, it won't be the end of the world. They have moved on in life and that is what happens."

Ashley, 38, and her husband Christopher French, 42, are expecting their second child together, while Vanessa, 35, is pregnant with her first child with spouse Cole Tucker, 27.
