The Dawson's Creek costars reportedly dated during season one of the hit show. During an interview with Rolling Stone in 1998, the actress said that Joshua was her "first love."
The duo certainly had a whirlwind romance. Nearly a month after calling off her engagement to Chris, Katie made her relationship with Tom public by appearing with him in Rome. In June 2005, Katie converted from Catholicism to the Church of Scientology, and a month later, the two announced their engagement.
In April 2006, the couple welcomed their daughter, Suri, and later that year they made things official by tying the knot during a lavish wedding in Bracciano, Italy. After five years of marriage, Katie filed for divorce in June 2012. Their divorce was settled 10 days later with custody of their daughter going to Katie.
While the pair met when Katie was still dating Tom, their relationship didn't turn into romance until almost a decade later when they were spotted dancing together at a star-studded Hamptons party in August 2013. After keeping their relationship under wraps for about three years, they made their first official outing as a couple at Clive Davis's annual pre-Grammys bash in January.
