He recently confessed to “making out with dudes” before jumping on the Ashlee Simpson Bandwagon and he’s an avid supporter of guyliner & unisex clothing, but Fall Out Boy bassist Pete Wentz is just as sweet as they come!

The 29-year-old emo rocker, who chatted with People on Saturday during the Ultimate Fighting Championship 86 afterparty in Vegas, said he is gearing up for fatherhood by reading numerous baby books on top of collecting useful tips from both his father and Joe Simpson, Ashlee’s pop.

In addition to acting as a human sponge, Pete has been speaking to his unborn baby, an activity he finds most satisfying.

“I talk to it all the time,” the theatrical cutie divulged. “The Expectant Father tells you that the woman, when she speaks, the baby hears her all the time. And the father’s voice isn’t familiar unless you talk to it, so I talk to it all the time.”

With that voice he should try singing into Ashlee’s belly as well!

“It tells you your partner’s moods month-by-month and week-by-week,” Wentz commented further. “It tells you why you’re feeling the way you are, how you can feel more involved in the pregnancy.”

Like any good man, waiting on his expecting bride is a major priority, and with Simpson-Wentz’s massive cravings for pickles, ice cream and green olives, Pete is a busy little beaver. As for the pregnancy itself, the musician says everything’s “going well.”

So well in fact that the lovebirds may wish to expand their family in the future: “This is the first one so we’ll have to base the next one on how we do on the first one,” Wentz declared.

Curious about the sex of their soon-to-be born child?

Well according to OK! magazine, sometime this month Ashlee and Pete created a gift registry at L.A. baby boutique Petit Tresor, where they were spotted purchasing an “over abundance” of blue items.

“They made it very clear that it was a boy,” a bystander relayed to the publication.

The couple reportedly grabbed several T-shirts and bibs with the words “Hunk,” “Loved” and “Yummy” printed across the fabric.

Think it was a decoy, or will we soon see a miniature Pete running around in bowler caps and makeup?
