Whoa! Justin Bieber almost took a spill Monday as he rollered out of meeting in Larchmont Village in LA. The singer wore $400 Segway Drift W1 e-skates on his Crocs and nearly wiped out next to cafe diners in the trendy neighborhood. But lucky him (and them) -- he high-fived the restaurant patrons instead of landing on their table!

Meanwhile, Hailey was off to see her stylist, of course, looking a bit more pulled together than her hubby. She wore the latest silk pajama-as-clothing trend with a Louis Vuitton bum bag strapped across her chest. We have to say, it looks like Justin was having a lot more fun!
