Pete Wentz reveals what he, newly-born son Saint have in common

LOS ANGELES, Sept. 1 (UPI) -- Pete Wentz is proud of his son Saint's sassy facial expressions.

The Fall Out Boy rocker told People magazine ahead of Sunday's MTV Video Music Awards his 12-month-old shares his dad's expressive eyebrows. "He gives me the same eyebrows that I give him when I'm like, 'Are you serious?'" Wentz said.

"There's nothing like getting that from a 1-year-old," he said. "I'm like, 'That's my look that you're giving me!'"

Wentz' first son with girlfriend Meagan Camper, and second son overall (he also has son Bronx, 6, with ex-wife Ashlee Simpson), was born a little over a year ago. Wentz explained why the couple chose Saint as their son's name on Instagram at the time, saying "I think at some point the name Saint came up because we thought he'd be a saint if he waited to arrive until his dad was home from tour, and he did. The name suits him."

"Meagan is a natural mom and it's amazing to watch her with him. The addition to our family is very exciting and Bronx is already planning everyone's Halloween costume," he wrote.
