You can never be too prepared for a baby!

That’s what Rebecca -- a Bachelorette superfan and an ICU nurse who helped save lives at the Las Vegas shooting -- found out as she prepares to become a first-time mom. Thankfully, Pampers and ET have teamed up to get her nursery perfectly ready for the baby!

“Oh my goodness. I love you,” Rebecca rejoices after Ali Fedotowsky-Manno surprises her with the trip.

“OK, so you are going to love the Target registry app, it only takes a few minutes to set up right on your phone, it's super easy,” the former Bachelorette star tells Rebecca.  “And then after your friends get you the gifts that they pick out, you get 15 percent off of whatever’s left on your list. But today we've got you covered! You ready to shop?”

“I know that one thing you can never have too much of is diapers,” Fedotowsky-Manno notes.

“We actually use these Pampers Swaddlers in the hospital, ‘cause they're so soft,” Rebecca reveals.

Sounds like Rebecca is pretty well stocked up for her little bundle of joy!
