Vanessa spoke about the new project in a glowing tribute to Ashley, which was posted on social media in honour of her 35th birthday on Thursday (02.07.20).

The 31-year-old actress wrote: "HAPPY BIRTHDAY TO MY OG BESTIE @ashleytisdale ash and I started from the bottom now we here!!! Lol but for real tho.

Ashley posted pictures of herself spending time in her garden, and wrote: "This is 35!! #wearamask #savelives (sic)"

Meanwhile, Ashley opened up on her friendship with Vanessa last year.

She said at the time: "We just have a connection and she's so awesome and one of my best friends. What I love about her is that she's so talented, and I think what we share is that we're really grounded people and I think that that's important, especially with what we do, is to stay grounded."
