New parents [artist id="1235716"]Pete Wentz[/artist] and [artist id="1241636"]Ashlee Simpson[/artist] are back painting the town red, and they can't stop talking about [article id="1599919"]their bundle of joy, Bronx Mowgli[/article], born just a few weeks ago. After hitting a Fall Out Boy concert Monday night, the happy couple were out again Tuesday night in Los Angeles at Travis McCoy's art show, where Pete gushed about his son.

"Every time I see my son, it looks like he's landing on the moon and discovering new rocks and stuff," he told People magazine. "I mean, every time he looks at his hand, it's like he's Christopher Columbus making it across the ocean. It's pretty awesome."

Despite Pete's fascination with art, he insists he's not going to push young Bronx into anything. He wants him to figure out his interests on his own. "I don't think it's appropriate for the nursery," he said of McCoy's artwork. "I'm not the kind of person that's going to push something on my kid. If he decides to go, 'Hey, dad, why don't you draw this for me or play this for me,' that would be cool."

Meanwhile, Ashlee has taken to MySpace to blog about being a new mom and how excited she is by it. "Motherhood is the most fantastic experience I have ever been through," she wrote. "Bronx makes me laugh and smile every day! ... I can't wait to spend [the holiday] with my new family. Christmas tree goes up tomorrow!"

She added, "I finally left the house for Fall Out Boy's show on Monday night, which was so good. Their new songs sound awesome live; I can't wait for their new record! And last night I went to Pete and Bronx's godfather Travis' art show."

Speaking of Travis McCoy, hanging out with baby Bronx has the [artist id="1904930"]Gym Class Heroes[/artist] frontman and girlfriend [artist id="1962774"]Katy Perry[/artist] thinking about babies themselves. "When I passed Bronx off to her, we both looked at each other," he told People at his art show. "Any young couple in love around another young couple in love, it's inevitable that you're going to get that spirit."
