The `Something Borrowed` actress - who announced her engagement to Muse singer Matthew Bellamy in April 2011 - said she wants to keep details of their special day firmly under wraps until after it happens but confirmed they already have a few details organised.

The mother-of-two - who shares son Ryder, seven, with her ex-husband Chris Robinson and son Bing, one, with fiance Matt, told USA Today newspaper: "I think until the day we get married, the answer is going to be, `We have no intention right now of getting married.` And then you`ll find out we got married.

"We have an idea. It`s starting to formulate but it`s a timing thing. But honestly, right now, Matt is touring. Ryder is in school. I`m working."

The 33-year-old actress - who models for makeup brand Almay - also opened up about her beauty regime and admitted she is a beauty product junkie.

She said: "I have quite a bit. I don`t use all of it. You buy makeup because it`s fun but you have your staples and for me, it`s the most natural-looking makeup. Sometimes you end up buying some sort of crazy yellow eye shadow, but I end up using the same stuff. I`m so loyal to specific products.

"I`m trying not to stay in the sun anymore. It bums me out. The sun makes me really happy. I`m really trying to stick on the SPF."
