"She wants to wait until after the baby," the 37-year-old actor told People. We've been very fortunate. We've waited and worked hard to really strengthen our relationship. We want it right.
"We're ready. I'm ready. She's been ready, but I think you know, we both come from broken homes and we want to succeed," he said of the 29-year-old Durham.

"... It's going to be a beautiful occasion," Wahlberg said Thursday at the Boston screening of his film The Happening. "Very intimate."
