Jennifer Aniston and John Mayer's relationship could be facing some friction after Jen made a heartfelt speech about cast mate Owen Wilson.

In a recent interview with a UK publication the actress could barely contain her respect and adoration for her Marley & Me co-star.

Jen gushed to OK! magazine, "Owen Wilson is so divine in this film.

"And I feel like, how brave of him, to walk through the year that he walked through."

Owen's biggest fan was reportedly fuming with pop star Pink after she claimed to have heard John say he only sleeps with stupid girls.
