Ashlee Simpson and Pete Wentz’s newborn son, Bronx Mowgli, is just fine, despite rumors that the 2-month-old suffered a broken arm this week.

Rumors that Bronx had been injured first surfaced after his mom cancelled an appearance at the Eleven Spa Vegas party on Wednesday. Celebrity tattles claimed that Ashlee stayed home because the baby’s arm was broken.

“It’s not true,” Simpson’s rep said on Thursday. “Everyone is fine.”
