Pop star Pete Wentz has been spotted rocking the baby back carrier look while out and about in New York.

The Fall Out Boy bassist has been pictured on the Celebrity Baby Blog taking son Bronx Mowgli for a stroll around Manhattan, where he made sure the little one was wrapped up in some snug children's winter clothing.

Indeed, to make sure the tot was kept doubly warm, the 14-month-old tot was encased in a cool baby back carrier as his dad wandered around the Union Square area of the city.

The pair have been snapped numerous times in recent months, often with mum Ashlee Simpson.

Earlier this month, the youngster was spotted sporting matching green and blue gloves and a bobble hat, while the family have also been seen enjoying the great outdoors at a city park.

Other celebrity babies seen sporting the latest in baby fashion include Lance Armstrong's son Maxwell.

The cycling star posted a snap of the pair on Twitter, which showed off one of the tot's latest all in one baby suits.ADNFCR-3005-ID-19586305-ADNFCR
