Rob Lowe, Guy Pearce, Grumpy Cat & More Hot Celebrity Sightings For June 18, 2014

So many photos, so little time. We spotted tons of celebrities out and about and attending events.

Rob Lowe was giving some serious good pose face (alongside a dog, literally) at the Barcelona photocall for Sex Tape. I am obsessed with this photo.

Guy Pearce looked pretty cute as he headed back to his hotel in NYC. I’m very excited about The Rover. 

And Grumpy Cat was busy, umm, being grumpy.

Launch the gallery to check out all the pics, and find out who was where and when!
