We're not saying anything here, but Justin Bieber and Hailey Baldwin have definitely been spending time apart since they've been back in LA following their vacay in Canada and Hawaii for Christmas and New Year's Eve. In fact ... we don't blame them!

That much time together is challenging for any couple, much less newlyweds and it's totally healthy to take some breathing room following a trip during which you were together 24/7 for two weeks.

Hailey was out running errands yesterday (actually she was doing more than running errands and we've got a gooood exclusive story coming soon ... stay tuned for that!) in a dangerously low-cut blazer with jeans and Chloe high-top sneakers and a somewhat misplaced green beanie. Still, she looks good in anything, but that accessory was a little weird ...

Speaking of weird headgear -- Justin wore a Stetson cowboy hat yesterday but his bottom half looked like LA skateboarder in shorts and Vans, while upstairs was 100% cattle drive!
