You can run (and probably post duck-face selfies while doing it) but you can't hide! Especially not with that unmistakable witchy mane!

After her 24-year-old boyfriend Tyga got detained by police yesterday, 17-year-old Kylie Jenner hid from photogs while stopping at CVS on Tuesday. For most teens, Veteran's Day is a fun-filled day off of school -- but when you are Kylie and you are homeschooled/not schooled (do we even know if she can read?), every day is a day off of school -- so it's today's just day to run some errands in Calabasas! But it looks like social media monster wasn't feeling the cameras today -- maybe it's because her new beau Tyga had a run in with Johnny Law yesterday!

On Monday, Tyga was racing to see Chris Brown (another model citizen) after shooting a music video and got detained (and handcuffed!) by police for unsafe lane changes and driving an unsafe speed, E! News reported.

The rapper was cited for the violations but eventually released by the authorities. However, his bodyguard was taken in on a weapons violation.

Kylie's big sis Kim Kardashian is already rumored to disapprove of the relationship because Tyga is her bestie Blac Chyna's ex -- so we can't imagine Kimbo is going to like this development!
