Bronx Mowgli Doing Just Fine

Ashlee Simpson and Pete Wentz's newborn son, Bronx Mowgli, is just fine, E! News has confirmed.

After the singer canceled an appearance at the Eleven Spa Vegas party on Wednesday, rumors flew that Ashlee stayed home because baby Bronx had broken his arm.

"It's not true," Simpson's rep said on Thursday, adding that Ashlee was planning to attend but canceled due to scheduling issues. "Everyone is fine."

Instead of hitting the party in Vegas, Ashlee instead chose to grab sushi at Nobu with some friends.
