Mark Wahlberg is finally doing the right thing!

The actor says that after his long-time girlfriend gives birth to their third baby, they'll finally take a walk down the aisle.

"She wants to wait until after the baby. We've been very fortunate. We've waited and worked hard to really strengthen our relationship. We want it right," says Wahlberg.

Who would have guessed that Marky Mark was so thoughtful and mature???

We're guessing wifey-to-be probably wouldn't have minded some immaturity in this instance!

Their kids Ella, 4 and Mike, 2, will be flower girl and ringbearer.

Will brother Donnie and his band New Kids on the Block be the wedding band?
