Amid Rumors Petra Collins is Dating Justin Theroux, Her BFF Selena Gomez Unfollows Her

Selena Gomez seems to be dealing with Justin-related drama — but this time, it doesn't have to do with the Biebz, and instead, her friend Jennifer Aniston's ex Justin Theroux.

Jen and Justin ended their two-and-a-half year marriage a month ago, and reports have already surfaced about him dating again. The mystery girlfriend? According to the Daily Mail, 25-year-old artist Petra Collins. 

Here's where things get tricky.

Selena is good friends with Collins, and the two have even worked together professionally a number of times (Collins directed Selena's Fetish video last year, for example). 

That's why it was so surprising when Selena unfollowed Collins on Instagram earlier this week. 

Perhaps it's all a big misunderstanding, but it does make sense that she'd ~side~ with Jen, since the two have been good friends for awhile.
