Olivia Wilde felt like she was suspended in "arrested development" when she married at the age of 19.

The 28-year-old actress wed Italian prince and filmmaker Tao Ruspoli as a teenager.

The couple divorced in 2011 due to "irreconcilable differences."

Olivia believes that making such a huge commitment in her youth adversely affected her maturation process.

"I really had a sense that I had stunted my growth," she said on TV talk show The Conversation With Amanda de Cadenet which airs this Thursday. "I think that's one of the things that made me feel so uncomfortable in my marriage. It was really no fault of my husband. It was me realising that I had sort of arrested development. I knew the only way I was going to grow the f**k up was to learn to take care of myself."

Olivia is currently in a happy relationship with beau Jason Sudeikis.

She is elated with life at the moment.

"A lot of people say, 'Wow! I feel like I'm seeing an old friend who I haven't seen in years.' It's a good feeling," she said. "I do feel more connected to myself and I feel more relaxed because I'm very open and raw. I feel like I've let people see me and I'm not longer trying to pretend I'm perfect."
