A little rocker is on the way! Fall Out Boy's Patrick Stump is expecting his first child with wife Elisa Yao — and very soon! The frontman announced the news during an interview with 102.7 KIIS FM on Wednesday, Sept. 3.

The 30-year-old revealed that he's been keeping the pregnancy under wraps, and he will become a first-time dad at the end of October.

"I'm about to have a kid or a tattoo. I'm like the snows of Siberia — just untouched," he said. "The band is in a crazy place right now because there's a lot of little kids running around."

Indeed, Stump's bandmate Pete Wentz welcomed his first child with girlfriend Meagan Camper on Aug. 20. (Wentz is already dad to 5-year-old son Bronx with ex-wife Ashlee Simpson. Simpson tied the knot with Diana Ross' son, Evan Ross, over the weekend.)

Stump and Yao — who tied the knot in October 2012 — are clearly in good hands. When asked what parenting advice Wentz has passed on, he replied: "You can never have enough Kleenex and baby wipes."
