If she's upset, she's not showing it!

Kristen Stewart went for a drive around L.A. this morning with her pal CJ, and he was grinning from ear to ear as he sat in the passenger seat of her ride. Now that Robert Pattinson has moved full steam ahead with new girlfriend FKA Twigs, let's hope she's not still carrying a torch for her former love.

The Twilight star has been back and forth from Japan while she films her upcoming movie Equals, so it's not like she's ever in one place long enough to strike up a romance. Then again, there are rumors she is secretly dating co-star Nicholas Hoult, so maybe she's mixing business with pleasure.

Eat your heart out R-Patz!
