I savor all of it because you are the greatest, Goose, AND it keeps getting better (as everyone told us)," she wrote alongside a series of photos of her with her little boy. Mandy Moore Instagram Speaking with Parents for the magazine's December 2021 cover story last year, Moore explained how her life has changed since welcoming Gus. "Not to sound cheesy, but all the clichés are true. Life is Technicolor now. It just makes sense in a way that it didn't before," said Moore. "I had no idea that this degree of love existed in the world." Asked whether baby Gus has had an influence on her creativity as an actress and a musician, the A Walk to Remember actress said motherhood is "going to change what I write about and, as an actor, what I'm able to access." "I have a new color to bring to the table that I didn't have before. It's going to impact the choices I make when it comes to work. Everything is different now," she added.
