Celebrity Engagement: Danny Masterson, Bijou Phillips Are Engaged

After 3 1/2 years of dating, Danny Masterson and Bijou Phillips are engaged, his rep confirms to Usmgazine.com.

The former That '70s Show star, 33, popped the question on Saturday.

Phillips, 28, was coy when asked if a wedding was in the works.

"It's not a yes; it's not a no," she told Us last April. "It just sort of is, you know?"

The two, who appear in the upcoming indie Wake, also just shot two films together: Made for Each Other and The Bridge to Nowhere directed by Blair Underwood.

How do they balance work and romance?

"I don't know -- we just do," Phillips told Us.

The trick to staying together? Not blabbing about their relationship.

Asked if she had any love advice she told Us: "I wish I did. This is my hidden tip -- not talking."
