Actors Josh Brolin, 33, and Minnie Driver, 31, are engaged, PEOPLE reports in its latest issue. No wedding date is set, but that, says the magazine, will give Brolin’s stepmother, Barbra Streisand, lots of time to sort out a guest list. (The singer is married to actor James Brolin, Josh’s dad.) The London-born Driver, whose past romances include John Cusack and her “Good Will Hunting” costar Matt Damon, fell for Brolin when they filmed 1998’s “Slow Burn.” He was previously married to actress Deborah Adair. Driver is also already chummy with Brolin’s children: Trevor, 12, and Eden, 8, as well as the elder Brolin. (Josh’s mother, Jane, died in 1995.) “It’s obviously they are very much in love,” Danny McKeever, Brolin’s auto-racing instructor — it’s a serious hobby for the actor — tells PEOPLE.
