Amanda Seyfried has "done a lot of therapy".

The 40-year-old actress feels thoroughly prepared for the next stage of her life, after attending numerous therapy sessions with her husband Thomas Sadoski and on her own over recent years.

The Hollywood star - who married Thomas in 2017 - told Who What Wear: "I know life is harder the older you get, but I also know that I'm pretty prepped because I've done a lot of work in the decade of my 30s.

"I've done a lot of couples therapy. I've done a lot of therapy alone. I've had insane amounts of conversations with psychologists and friends who are psychologists that I feel like I have a lot of self-knowledge. It's not everything, but it certainly goes a long way."

Amanda has already enjoyed huge success in her career, but the actress is determined to keep testing herself.

The movie star is actively seeking roles that are "really scary".

She explained: "I feel like I have to keep choosing things that terrify me - within reason, right? I'm not gonna jump off a cliff or jump out of an airplane, but I need to sink my teeth into something that is really scary because I know I can do it, and I know I'll be better for it."

Amanda made her feature film debut in the teen comedy Mean Girls back in 2004.

The movie - which also starred the likes of Lindsay Lohan, Rachel McAdams and Tina Fey - proved to be a huge hit with cinemagoers, and Amanda is still regularly reminded of the project.

Asked if she's re-watched Mean Girls, Amanda told Variety: "No. It's on often enough, though.

"I love it. I really love seeing my face on people's T-shirts. I'm a little resentful because Paramount still owes me some money for the likeness. Every store sells Mean Girls T-shirts with our faces. Don't I [get something from that]? Even the girl at TSA tells me it's her favourite movie."
