Chris Klein and Laina Rose Thyfault have announced their engagement

The happy couple have been quietly dating since they were introduced at a mutual friend's wedding. And it probably won't be long before they're heading to the altar. "

Neither one is interested in a long engagement," a pal told , "so they're shooting for a summer 2015 wedding." Chris has maintained a low-profile in recent years – but opened up about his struggles with sobriety back in 2010. After his second DUI that year, the actor voluntarily checked himself into a 30-day treatment centre to deal with alcoholism, and a few days later spoke candidly about his battle. "It got to the point where I was a fragile shadow of the young man that came into this business," he told . "Today, I'm the luckiest guy alive." Prior to finding love with Laina, Chris dated Ginnifer Goodwin, from 2006 until 2008. He started a relationship with Katie Holmes in January 2000, and the couple got engaged around Christmas 2003, before calling time on their romance in March 2005.
