Andi Dorfman and Josh Murray Andi Dorfman and Josh Murray

Their engagement was just revealed on The Bachelorette, but Andi and Josh already have babies on the brain!

"I mean, I would have [had] a baby yesterday!" Josh told Tuesday after the finale. "We'll wait until she's ready and then we'll start popping them out one after another."

The Bachelorette Finale: Who did Andi choose?

On Monday's finale, Andi said goodbye to Nick prior to the final rose ceremony and chose Josh, who then proposed. Although Andi admits she wasn't positive that Josh was "the one" until that morning, she says he emerged as a definite front-runner after their night in the Fantasy Suite. "[It] was really telling because off-camera Josh was the same person that he was on camera," she told us. "I remember looking at him and saying, 'It's like you're my best friend.'"

For Josh, he's had strong feelings since their first kiss. "I was developing stronger feelings for her after our first kiss at the second rose ceremony, but each and every day, my feelings kept getting stronger," he said. "By the time hometowns hit, I knew I wanted to make her my wife — I was totally in love with her."
