While they're not floating on a chunk of ice in the Atlantic declaring undying love to each other, Kate Winslet and new boyfriend, model Louis Dowler, appear to be very much enjoying their time together.

Winslet, 35, separated from former husband, director Sam Mendes in March after almost seven years of marriage. The couple have two children together. Winslet, who just celebrated her birthday, was seen in New York carrying a huge bouquet of roses according to the Daily Mail. Reports say that she and model Dowler, 34, have been dating for just around three months. The couple, who were introduced by a mutual friend at a party, have been inseparable.

"Kate hasn't been this happy in a very long time," one source said. The actress is currently in Chicago shooting the film Contagion, alongside Gwyneth Paltrow, Jude Law and Matt Damon. –AMY LEE
