Justin Bieber stepped into the role of protective big brother on Thursday as he happily carried younger sibling Jaxon in his arms as he left his hotel in Madrid, Spain, the latest stop on what so far has been a tumultuous European tour.

Justin, 19, held his baby bro out before his Beliebers and the paparazzi, and other than covering his ears from all the noise, Jaxon was all smiles as he and the rest of Justin’s close-knit clan stayed by the singer’s side prior to Thursday’s gig in the Spanish capital.

Jeremy, the kids and Bieber’s mom, Pattie Mallette, were in town to support the hitmaker after the rough week he had, which included collapsing onstage in London, lunging at the paparazzi, canceling a concert in Portugal and battling reports he’s out of control and rehab-bound.
