Kelly Osbourne with her son

Kelly Osbourne appeared calm and collected as she pushed her infant son in a stroller to a friend’s house in Los Angeles this week.

Kelly Osbourne and her son haven’t been seen together since Sydney’s birth in November. The 38-year-old television star was spotted in Los Angeles pushing her son up a hill in a black Doona car seat and stroller combo on her way to a friend’s house.

Her baby, whom she shares with her musician partner Sid Wilson, was obscured by the stroller’s safety netting.
