'Jealous' Jennifer Aniston Worries Justin Theroux Is Getting Close To Another Woman

Jennifer Aniston doesn’t have her own Instagram account, but an insider says that the actress still browses the photo app online.

And she doesn’t love seeing that hubby Justin Theroux, 46, and his makeup artist Jenn Streicher have been popping up in each other’s posts.

“Even though they weren’t inappropriate and Jenn is married, it still hit a nerve with her, so she let him know,” dishes the insider.
