Featured on the cover of InStyle's February issue, the 36-year-old actress says she would love to slow things down a bit. We are living in a time when we have such expectations of immediacy. Everything is instantaneous, everything's out there, she told InStyle in an interview.

The couple got engaged during a vacation in Sun Valley, Idaho, according to the E! Online. She's yearning to get married and have kids, a source told US weekly.  Barrymore and Kopelman had dated briefly in 2010 but rekindled their love for one another last year, which was made public in February after they were spotted arm-in-arm strolling along Fifth Avenue in New York City.

Speaking to InStyle about her fiancé, Barrymore said, It's just the best! We go on group trips and spend holidays together - there's a lot of love! And that is really nice and very different from the way I grew up, which was more unstable and inconsistent, with a lot of highs and lows. It's funny, when I was younger; I used to say I'd hate a flat line - that I want the ups and the downs, the roller coaster. But I'm actually really enjoying the flat line.

This will be Barrymore's third marriage. She was previously married to Jeremy Thomas in 1994 and filed for divorce just two months after eloping. In 2001, she married to comedian Tom Green who she also divorced just five months after their wedding ceremony. This will be Kopelman's first marriage.

In the past, Kopelman has dated actresses including Sarah Roemer and Lara Flynn Boyle, the New York Post reported.  His $1.04 million apartment was named Best Bachelor Pad in LA by Elle Décor Magazine.
