The `One Day` actress - who has been in a relationship with Adam Shulman for three years - admits she has recently changed her mind about the institution after witnessing her best friend walk down the aisle.

Speaking to Chelsea Handler for Interview magazine, she said: "I am open to marriage, actually. I just went through a phase where I wanted to look at it from every angle to make sure that I wasn`t just falling in step with some kind of prescribed fantasy.

"I was at my best friend`s wedding just two days ago, and I watched this person who I love like a sister, and who has changed my life and continues to change my life for the better, who I feel as close to as I do my family, commit herself to a man who she loves, and I watched how happy it made her.

"I mean, she looked like she was riding a bubble the whole night. I thought, `Weddings are important because they celebrate life and possibility.` "

The brunette beauty admitted Adam is thrilled by her changing attitude because she has previously been so outspoken about not wanting to tie the knot.

She added: "There`s a smile on [Adam`s] face - mainly because I`ve been such a pain the past few months, going, `Well, is marriage really a tool of oppression?` or `It was once just an exchange of property!` I have been utterly without romance regarding marriage for the past few months, so I think he`s relieved that I`m kind of over it."
