Kate Winslet's Romantic History Through the Years

Winlset met her first love, actor Stephen Tredre, when she was 15 years old. Tredre was 28 at the time. "Stephen made me feel secure and embraced," she told Parade magazine in 2006 (via People). "Stephen was very inspiring. He had this extraordinary zest for life. My life revolved around him."

Tredre was diagnosed with bone cancer shortly after, and they split when his cancer was in remission. "I don't know why. I was so young, when I look back on it. Only 19. How could I have left a person who was so unwell? I thought Stephen was going to be all right," Winslet added.

Tredre died in 1997, the same week that "Titanic" debuted.

Winslet and Jim met in 1997 on the set of "Hideous Kinky," in which she starred as Julia and he worked as a third assistant director. The two wed in 1998 and split in 2001, just one year after welcoming their daughter, Mia Threapleton. Winslet opened up about her relationship with Jim in a 2006 interview with Parade (via CBS News). "I thought I wanted to be with him," she explained. "I was dealing with the pain of having lost Stephen and 'Titanic' coming out. Jim was just a regular guy, and that had a big impact on me."

Jim also spoke out about his split from Winslet in an interview with The Guardian in August 2007 and shared how he worked things out with her husband at the time in regards to their daughter. "I have nothing but the utmost respect and admiration for his work, and subsequently, I've found out over the years that he's a fantastic person to be in Mia's life," he said. "The hardest thing with divorce when children are involved is working out how the new relationship will work. You are obligated to generate new terms of friendship quickly, and I had beers with Sam as soon as possible so that there was never going to be this sense that we couldn't talk."

Winslet then moved on with Sam, whom she wed in 2003. Their meeting wasn't by chance, but rather it happened when Mendes had hoped to cast her in two plays he was directing at London's Donmar Warehouse theatre, though she had no intention of taking on the roles. "Didn't want to do the plays, definitely wanted to get his phone number," she told Vanity Fair in November 2008. The two welcomed their son, Joe Mendes, in 2003, but announced their split in 2010. Their divorce was finalized in 2011.

In the same Parade interview, Winslet gushed over her immediate connection with Sam. "I walked away dazzled, thinking, 'What the hell was that?' I knew this was the person I was meant to be with," she shared. "I was terrified. I didn't tell anyone I had this feeling, not even my mum. I had no idea if Sam felt anything for me."

Winlset also spoke about how the media coverage surrounding her two divorces was brutal, but it wasn't the worst thing that had happened to her: "It was shattering, but it was nothing compared to losing Stephen."

Winslet had a brief romance with the model. According to the The Mirror, the two split in November 2010 after just four months of dating. Dowler was left stunned and hurt by Winslet's decision to call it quits on their relationship. "I don't think Kate behaved well and it is still very raw for me," Dowler told the Daily Mail a year later. "I was in love with her and you can't switch that off overnight. I'm not sure Kate treated me well."
